Mukund Manohar   7 years AGO

26+64 = (2*6) + (6*4) = 12 + 24 = 36 = 63 (Digits are reversed)
32+48 = (3*2) + (4*8) = 6 + 32 = 38 = 83 (Digits are reversed)
Similarly,
68+39 = (6*8) + (3*9) = 48 + 27 = 75= 57 (Digits are reversed)

multiply the numbers and add both...then reverse the sum
1)26+64=63
2*6+6*4=12+24=36
reverse the digits of 36 is 63

2)32+48=83
3*2+4*8=12+32=38
reverse of 38 is 83
in the same way 68+39

Market price is Rs.1500. on which shopkeeper gives 15% off means Rs.225 so 1500-225=1275. Now again shopkeeper gives 20 off on new price means 20% on 1275 = 255. So 1275-255=1020. Shopkeeper again give 25% off no new price means 25% on 1020 i.e. Rs.255 so 1020-255=765.

so finally we have to pay Rs.765 only.

15 Jun 2017 Race

A and B run a km race. If A gives B a start of 100 m, A wins by 20 sec and if A gives B a start of 50 sec, B wins by 30 m. The time taken by A to run a km is

OPtion

2) 190.846 sec
3) 192.846 sec
4) 196.846 sec

6) 234.94 sec
7) 236.94 sec
8) 238.94 sec
9) 240.94 sec
10) None of these

Solution

Answer: 196.846 sec
Let time taken by A to run 1 KM be a and by B be to run 1KM be b
If A gives B a start of 100 m, A wins by 20 sec

Distance travelled by A = 1000

Distance travelled by B = (1000-100)=900

Time taken by B to run 900 m - Time taken by A to run 1000 m = 20 sec
900b/1000 - a = 20 sec
a = (900b/1000) - 20


If A gives B a start of 50 sec, B wins by 30 m

Distance covered by B in b seconds - Distance covered by A in b-50 seconds = 30m
1000 - 1000*(b-50)/a = 30
=> 970a = 1000b - 50000

970*(900b/1000) - 970*20 = 1000b - 50000
873b - 970*20 = 1000b - 50000
=> 127b = 30600
=> b = 240.94

so a = (900b/1000) - 20 = 900*240.94/1000 -20 = 196.846 sec

Option 4)

Correct Option: 4 Best Solution (4)

G.S.Kantharao   7 years AGO

Let A runs 1000mts in = p seconds
B runs 1000mts in =q seconds.
Step 1: If A gives B a start of 100mts.
That means A ran 1000mts, B ran 900mts
Time difference = 9q/10 -p= 20sec
9q-10p=200-------Eqn.1
If A gives B a head of 50 sec
Then the distance covered by B in q sec.- the distance covered A in (q-50)sec=30mts
That is 1000- 1000(q-50)/p= 30
1000(q-50)/p=1000-30=970
10q-500=9.7p
10q- 9.7p=500
100q-97p=5000--––--Eqn.2
By the method of elimination
We can get 127p=25000
Then the time taken by A to complete the race = p sec = 25000/127 = 196.85sec
Hence the right option is 4.😇😇😇👌👌👌

Let, Time taken by A=a & B=b
If gives a start of 100m A wins by 20s
Distance travelled by A=1000m then
B=1000-100=900m
Time taken by B to run 900m- Time taken by A to run 1000m=20s
(900*b/1000)-a=20...(1)
If A gives B a start of 50s, B wins by 30m (b-50)
=> 1000- (1000/a)* (b-50)=30
=> 1000b- 50000=970a...(2)
eq1*eq2, we get:
(90*97/100)- 97a=20*97
=>873b-970a=1940...(3)
Now, eq2-eq3;
=>1000b-873b=50000-19400
=>127b=30600
=>b=240.94
Substituting the value of b in eq1;
(90/100)*240.94-a=20
=>a=196.84

A gives B 100 meter start and wins the race by 20 sec=(1000/900-20b)=X
if A gives a 50 sec start then, wins by 30 m=(970/950-50b)=Y
X=Y
by solving the value of b is 4.1503
let speed of A be x..the (1000/900-20(4.1503))=(x/4.1503)
then the value of x will be 5.0799
time taken by A to complete the 1000 meter race is 1000/5.0799

P can do a work in 12 days. Q can do the same work in 8 days and R can do the same in 6 days. Q and R start the work and leave after 2 days. P finishes the remaining work in X days. What is the value of 1.1X?

OPtion

1) 4.5 days
2) 5.05 days
3) 4.75 days
4) 6.5 days
5) 5.0 days
6) 0.55 days
7) 5.75 days
8) 2.5 days
9) 5.5 days
10) None of these

Solution

Amount of work done by Q and R in 2 days = 2*(1/8 + 1/6) = 2*7/24 = 7/12

Amount of work remaining after 2 days = 5/12

Amount of work done by P in 1 day = 1/12

1/12 work is done by P in 1 day
5/12 work is done by P in 5 days
Hence X=5
So 1.1X = 1.1*5 = 5.5

Correct Option: 9 Best Solution (13)

tumati koushik   7 years AGO

P 1 day work =1/12
Q 1 day work =1/8
R 1 day work =1/6
(Q+R) 1 day work =1/8+1/6=7/24
(Q+R) 2 day work =(7/24)*2=7/12
remaining work= 1-7/12=5/12
5/12=5(1/12)=5*(P 1 day work)

therefore,P can complete this work in 5 days

Like? Yes (2) | No   

palak Jain   7 years AGO

Let total work unit=24
P 1day work =2units/day
Q 1 day work =3 units/ day
R 1 day work =4 units/ day
Q+R 1 day work = 7 units /day
2 day work of Q nd R= 14 units
Work left 10 units
P can complete that work in 5 days working 2u/day
So ,1.1*5=5.5

Like? Yes (3) | No (1)  

G.S.Kantharao   7 years AGO

P,Q,R can do in 12,8,6 days.
Their capacities per day are 1/12, 1/8, 1/6 resectively.
If Q and R joined then their capacity per day is = 1/8 + 1/6=7/24
If they together worked for 2days they complete = 7*2/24=7/12
Remain part = 1- 7/12= 5/12
If P completes the work in X days in then X =5/12. *12/1 = 5
Then 1.1X = 5.5 days.
Hence the right option is 9.,👈

BHAVANA   7 years AGO

let the work will be in 120
p can do work in 12 days means for one p can compleate 10
q can 15 and r can 20
if q and r works for 2 days then 15+15+20+20= 70 work will be compleated
remaining 50 work wiil be compleated in 5 days by p
means x is 50
50*1.1=5.5

jyothi chhabria   7 years AGO

let total unit of work be 48 units
p=4 units
q=6 units and r=8 units
q+r worked together for 2 days I.e 14 units ×2 =28 units
remaining work is completed by p I.e 48-28=20 units
p one day work is 5 units
then 20 units can be done in 5 days
1.1*5=5.5 days

Like? Yes | No   

Mukund Manohar   7 years AGO

P's 1 day's work = 1/12
Q's 1 day's work = 1/8
R's 1 day's work = 1/6
2*(1/8 + 1/6) + X/12 = 1
=> 2*(7/24) + X/12 = 1
=> 14/24 + X/12 = 1
=> 2X = 24-14
X = 5
So, 1.1X = 1.1 * 5 = 5.5 days

Like? Yes | No   

ganesh chemanchula   7 years AGO

Q's 1 day work 1/8
R's 1 day work 1/6
(Q+R)'s 2 days work=(1/8+1/6)*2=14/24
Remaining work after 2 days= (1-14/24)=10/24
P can complete 1 work in 12 days..then in how many days P can complete 10/24 work..that is (10/24)*12=5..value of X is 5..then value of 1.1X=1.1*5=5.5
option (9).

Like? Yes | No   

Disha agarwal   7 years AGO

when q and r do work for 2 days the total work done will be = (1/8 + 1/6)*2 = 7/12

remaining work = 1-(7/12) = 5/12
so
work done by P in one day = 1/12
so total days P will take to complete 5/12 work are = 5 days

so x = 5 days
x*1.1 = 5.5 days

Like? Yes | No   

Mayur Shinde   7 years AGO

If P is doing 100% work in 12 days means he is doing 8.3% work per day similarly Q is doing 12.5%work per day and R is doing 16.6% work per day

so Q+R= 2(12.5+16.6)
so Q+R= 58.2

means Q and R finished 58.2% work in 2 days. Remaining work is 41.8%. And P can do 8.3% work per day.

so 41.8/8.3=5

means P will take 5 days to complete remaining work. So value of X is 5

so 1.1X= 1.1*5 = 5.5

VAIBHAV SRIVASTAVA   7 years AGO

(Q+R ) 1 days work={(1/8)+(1/6)=7/24}
(Q+R) work in 2 days=(7/24)*2 =7/12
remaining work= 1-(7/12)=5/12
work done by P in 1 day =1/12
so remaining 5/12 work done by P = (5/12)*12= 5 days
so X=5
so 1.1X=1.1*5=5.5 days
