apply shridharacharya rule (-b +_√(b^2-4ac))/2a

Option 3)

Correct Option: 3 Best Solution (10)

Chandni Maurya   10 years AGO

ans= (3)432 rs

let x be the price of water bag.

according to ques,
(x-100)*0.5*.5*.5*.5 = sq. rt (x)
(x-100)*0.0625 = sq. rt (x)
0.0625 x - sq. rt (x) - 6.25 = 0 --- (1)

solving equ. 1
sq. rt (x) = 20.806 rs & - 4.80 rs
= 20.806 (neglecting -ve value)

=> x = (20.806)^2
x = 432.889 rs

x = 432 => opt (3)

S.SHAFI   10 years AGO

Let the prize of water bag is x..
The prize of water bag is greater than 400rupees,
so x > 400
The scheme is 50%+50%+50%+50% off after giving a discount of 100,
so (1/2)*(1/2)*(1/2)*(1/2)*(x-100) is the amount left and it is equal to square root of its original value

so, (x-100)/16 = sqrt(x);
squaring on both sides, we will get

x^2 + 10^4 - 200x = 256x

x^2 - 456x + 10^4 = 0

x = {456 + sqrt(456^2 - 4*1*10^4)}/2

x = 432

Leelanand Kumar Yalla   10 years AGO

Let The Cost of water Bag is 400+x;
After Giving a Discount of 100 Rupees it is 300+x;
And again A scheme of Discount 50%+50%+50%+50%..
I.e., (300+x)*50/100*50/100*50/100*50/100= (300+x)/16;
The Original Price of Water Bag is 400+x;
square root(400+x)= (300+x)/16;
By solving This we will get x= 32.8999756;
so the actual Value of Water bag is 400+32.899= 432 Rupees by Removing Paisa...... This is the answer...

Vinay Gupta   10 years AGO

Let list price = x^2
and cost price = x
and total off after discount of 100 rs. = 50%+50%+50%+50%=375/4%

So the equation becomes
(x^2-100)[{1-(375/4)}*100]=x
=>(x^2-100)[(400-375)/400]=x
=>(x^2-100)*(25/400)=x
=>(x^2-100)*(1/16)=x
=>x^2-100=16x

initially take the prize of water bag as (400+x)
then apply discount of 100

then apply 50% discount on (300+x)
we get 150+(x/2)
subtracting (300+x)-(150+(x/2))
=150+x/2
repeat the above process on the amount obtained after subtraction in each case three more times
after that,
sqrt(400+x)=(18.75+(x/16))

firstly it divide the total words in two parts and then takes its opposite value as result
EXAMPLE1: ABHISHEK=IHBAKEHS
{A B H I} {S H E K} So Reverse of 4 one is:
={I H B A} {K E H S} = IHBAKEHS
ANOTHER ONE EXAMPLE ALSO FOLLOW THIS ABOVE METHOD:
EXAMPLE2: MANINDER = INAMREDN
{MANI} reverse value is= INAM
{NDER} Reverse Value is= REDN
so reversed value is INAMREDN.

Then SURENDER Divided in two equal part which have {SURE}&{NDER}
now the reverse value of SURE= ERUS
And reverse value of NDER= REDN
So lastly answer is SURENDER = ERUSREDN.

A jar of 10 litres contains 4 litres milk and another of 6 litres is filled completely with water. 6 litre mixtures are removed to second jar after pouring all the water of second jar in first. After then the process is revised with 4 other jars of 6 litres filled with water completely. What will be the amount of milk remained in 10 litre jar finally.

OPtion

1) 0.52675
2) 0.01024
3) 0.12500
4) 0.04096

6) 0.40000
7) 0.66667
8) 1.50000
9) 0.06400
10)None of these

Solution

In every mixing process 4 part of milk is present in 10 part of mixture. Hence for this process of 5 steps remaining milk in 10 litres jar is
4×(4/10)×(4/10)×(4/10)×(4/10)×(4/10)
=0.04096

Correct Option: 4 Best Solution (12)

ROHIT UPADHYAY   10 years AGO

if the solution is 100%
after first process solution left = 40%
because process is revised with 4 other jars of 6 liters filled with water completely
and in each time solution left 40% so we have to find 40% of the solution in each time
so again from 40% = 40*(40/100) =16%
= 16*(40/100) =6.4%
= 6.4*(0.4) =2.56%
= 2.56* 0.4 =1.024%
so finally after 4 other jars solution left =1.024%
so milk left = 4*1.024/100 =0.04096

Like? Yes (16) | No (3)  

KRISHNAN   10 years AGO

The First Jar contains 4 ltr milk and 6 ltr water is added so the % of milk in the jar is 40%
So after removing 6 ltrs of mixture the remaining 4 lts of mixture contain 40% milk or 1.6Lts of milk

Now if this process is repeated for first jar
1.6 lts milk and 8.4 Lts water milk % is 16%
and milk left in 4 lts mixture is 0.64 lts

For second Jar repeataion
0.64 lts milk and 9.36 Lts water milk % is 6.4%
and milk left in 4 lts mixture is 0.256 lts

For third Jar repeataion
0.256 lts milk and 9.744 Lts water milk % is 2.56%
and milk left in 4 lts mixture is 0.1024 lts

For Fourth Jar repeataion
0.1024 lts milk and 9.8976 Lts water milk % is 1.024%
and milk left in 4 lts mixture is 0.004096 Lts

Milk and Water are in the ratio of 4:6;
now 6 Liters Mixture Removed means from both milk and water subtract the Mixture of 6 Liters;
i.e., 4-(4/10)*6=1.6 Liters Milk available now;
like this from water 6-(6/10)*6+6= 8.4 Liters water available after Removing 6 Liters mixture.
so now the ratio of Milk and Water is 1.6:8.4;
again do the same procedure of removing 6 Liters mixture and add 6 Liter water... 1st time
1.6-(1.6/10)*6=> 0.64 Liters Milk;
8.4-(8.4/10)*6+6=> 9.36 Liters water;
again;
milk:water= 0.64:9.36; 2nd time
0.64-(0.64/10)*6=>0.256 milk;
water= 10-0.256=9.744;
again;
milk:water= 0.256:9.744;
0.256-(0.256/10)*6=> 0.1024 milk; 3rd time
water= 10=0.1024=9.8976;
now milk:water= 0.1024:9.8976; 4th time
0.1024-(0.1024/10)*6=>0.04096 milk;
water= 10-0.04096= 9.95904;

Mallikharjuna   10 years AGO

intial M:W=4:6
6 liters of mixture drawn form jar then remaing milk in water is=4-(4*6)/10
=1.6
repeat same procedure for 4 more times
1 st time remaing milk is= 1.6-(1.6*6)/10
=0.64
2 nd time remaing milk is = 0.64-(0.64*6)/10
=0.256
3 rd time remaing milk is 0.256-(0.256*6)/10
= 0.1024
4 th time milk is 0.1024-(0.1024*6)/10
=0.04096.

hence remaing milk is = 0.04096.


first milk in jar is 2^2,

amit choudhary   10 years AGO

Because on mixing water and milk we can see that in 1st jar 1 litre mixture contains 0.4 litres of milk and 0.6 litres of water.
So for 1 jar remaining water is (4*4)/10=1.6 litres milk
for second jar (1.6*4)/10=.64 litres milk
for 3rd jar (.64*4)/10=.256 litres milk
for 4th jar (.256*4)/10=.1024 litres milk
for last(5th) jar (.1024*4)/10=.04096 litres milk..
Here we are multiplying it by 4 because the remaining amount of mixture in each jar after adding 6 litres of water in it is 4 litres and we have to find out quantity of milk in that 4 litres mixture..

Let we know cost price=48
packet of toffee contains 74 toffee and each sold in 1 rupee
So total toffee Selling price =74
According formula:
Profit in percentage=
[(Selling price-Cost Price)/cost price]*100
=[(74-48)/48]*100
=54.166667
=54 approximately
Answer:- So Profit is 54%

Zunaira Jamal   10 years AGO

54 is the Answer...
1pkt -> 48rs
ie., 74Tofee -> 48rs
then 1 tofee -> 48/74Rs

If 1 tofee is 1 rs, then profit is = (1-48/74)Rs
= 13/37 rs

Now profit% = (13/37)/(48/74)*(100)
= 325/6 = 54.166 ~ 54%

the cost of the packet is 48 were as if the toffees are sold at rs 1 per toffee...then all the toffees will cost 74

What will be the difference of cost of an object of 1000 rupee if a discount of 10% +10% +10% is provided by the first shopkeeper and 30% by the other.

OPtion

1) 10
2) 30
3) 0
4) 28
5) 20
6) 11.1
7) 25
8) 29
9) 9
10)None of these

Solution

In first case the price of the object is 1000* 0.9* 0.9* 0.9 = 729
In second case it is 1000* 0.7 = 700
Difference is 729 – 700 = 29

Correct Option: 8 Best Solution (48)

Vignesh   11 years AGO

Discount provided by the first shopkeeper :
10% of 1000 = 100 --> 1000 - 100 = 900
10% of 900 = 90 --> 900 - 90 = 810
10% of 810 = 81 --> 810 - 81 = 729

Discount provided by Others :
30% of 1000 = 300 --> 1000 - 300 = 700

So, the difference is

729 - 700 =29

ROHIT UPADHYAY   11 years AGO

cost of an object = 1000
in first case cost is 1000 *(100/110) *(100/110) *(100/110) = 729
or
1000* 0.9 =900
900 * 0.9 =810
810 * 0.9 =729

in second it is 1000 *100/130 = 700

so, Difference is 29

madanpal vishwakarma    11 years AGO

M.p of the item is Rs.1000
1. 10 % discount is given so the price is Rs.1000-(10/100)*1000=900
2. again 10 % is given on Rs.900 so the price is 900-((10/100)*900)=810
3. Again on Rs.810 10% is given so the Final Selling Price is 810-((10/100)*810)= Rs.729

Whereas another Shop keeper give 30% directly so its selling price is Rs.700

So the difference is = 729-700=Rs.29

we have 1000 rupees...
take only for first shopkeeper...
10% of 1000... = 100 and remains 900
then he give second time 10%
so, 10% of 900 is 90 and remains 810..
then he give third time also 10%
so, 10% of 810 is 81 and remains 729 ..
finally Out of 1000 he give 271 rupees discount...
...
For other user the simply give 30% discount..
so 30% of 1000 is 300...and 700 is price..

first shopkeeper cost is 729 and other shopkeeper cost is 700, so 729-700 = 29..

Cost of Object is 1000 rupee.

First 10% discount means 100.(10% of 1000=100). Net price is 900.
Second 10% discount on 900 only. That is 90 (10% of 900). Net Price is 810.
Third 10% discount on 810 only. That is 81 (10% 0f 810). Net Price is 729.

If he gives 30% discount at time that is 300 (30% of 1000), the net price is 700.

krishna   11 years AGO

first ten percent will reduce 1000 to 900 next 10 %
reduce 90/- and next 10% in 810 is 81 totally 729 is the cost .By giving over all cost reduce of 30 % it will reduce to 700
hence the difference is 29/- only
