. A vessel contains mixture of milk and water in the ratio of 7:1 respectively. 24 liters mixture
is removed from the vessel and if the quantity of remaining milk in the vessel is 56 liters, then find
quantity of water in the vessel initially.

Reply Like? Yes | No

(26 Days ago)

Ans: 11 liters

Let, initial mixture contains milk=7x and water=x
Then, quantity of remaining milk after removing 24 liters of mixture=7x - 24*(7/8)=56
56x - 168 = 448
x = 11
.'. Quantity of water in initial mixture = x = 11 liters.

Very simple 11lts.
After removing 24 lts the mixture is in the same ratio
Milk:water=7:1=56:w=>w=56*1/8=8lts
In 24 lts removed mixture=24*1/8=3lts.
So total water is 11 ltd.

A person sold an article for 1840 Rs. And profit incurred will be 12.5% more than the loss incurred when article is sold for 1500 rs. At what price it should be sell to get 20% profit?

Reply Like? Yes | No

(1 Month ago)

Ans: Rs. 1992

Let CP=Rs. x, then Profit when SP is 1840 = (112.5/100)*Loss when SP is 1500
(1840-x) = (112.5/100)*(x-1500)
184000 - 100x = 112.5x - 168750
Solving, we get x = 1660
So, SP when profit is 20% = 1660*(120/100) = 1992 Rs.

There is a splendid fountain in the heart of Paris Tourists throw coins into the fountain in the belief that their wishes would come true. At the end of each day, a group of urchins jump into the water and pick up the coins. It is a tradition that they share the amount equally On Friday, had 5 urchins not shown up due to rain, each of those present would have received a Euro more But had it been a sunny day and there had been 15 more urchins, each would have received 2 Euros less, Find the total number of Euros in the fountain on Friday

Let x urchins gets y Euros each, when all urchins are present, then total Euros=x*y
As per given conditions, (x-5)*(y+1)=xy ⇒ x-5y=5 ---(i) and
(x+15)*(y-2)=xy ⇒ -2x+15y=30 ---(ii)
Solving above equations, we get x=45, y=8

If the sum of the first 43 terms of an arithmetic progression is 2967, then find the sum of the 11th and the 33rd terms of the same series.

Reply Like? Yes | No

(3 Months ago)

S43=43(2a+42d)/2[through formulaSn=n{2a+(n-1)d}/2]
So S43=43(2a+42d)/2=2967
Now T11=a+10d
T33=a+32d
T11+T33=2a+42d=2967*2/43
=138

Like? Yes | No

(3 Months ago)

Ans: 138

For A.P. series, here n=43, S=2967. If First term=a, Difference=d, then sum of an A.P. series S=(n/2)[2a + (n-1)d]
2967 = (43/2)(2a + 42d)
69 = a + 21d ---- (i)
Sum of 11th term and 33rd term = (a + 10d) + (a + 32d) = 2a + 42d = 2 x (a + 21d) = 2 x 69 = 138

When 1 is at unit place, total 5 digit numbers = 4 x 3 x 2 = 24

New Public School has a circular layout. The school has teachers specializing in various subjects. All

classrooms of the school are equally spaced apart and located along its perimeter. Each teacher needs

to take 4 classes in a day. There is a strange rule. The first and last class has to be in the same class

roun. The other two classes have to be at two other distinct class rooms.

Ram is a math teacher. He never teaches two successive classes at two adjacent classrooms. How many distinct trips to class rooms are possible for Ram if there are 9 class rooms in the school?

In a day
First & last room should be same
Let's choose it arbitrarily, next class can be chosen in 6 ways
Because same room cannot be chosen & neighboring rooms are also not allowed
Round represntations of class: 1 2 3 4 5 6 7 8 9. 1....

Let first one be 1
Then second can be 3 4 5 6 7 8
For 3, third class can be any of 5 6 7 8
For 4, third class can be any of 2 6 7 8 9
For 5, third class can be any of 2 3 7 8 9
For 6, third class can be any of 2 3 4 8 9
For 7, third class can be any of 2 3 4 5 9
For 8, third class can be any of 2 3 4 5 6
For 9, third class can be any of 2 3 4 5 6 7
And fourth class will be again 1

So total possible classes keeping first class constant is: (4)+(5*5)+(6) = 35

Similarly first class can be changed in 9 ways => Total possible trips per day = 9*35 = 315

If the capacity of a cylindrical tank is 4004 m^3 and the diameter of its base is 14 m, then find the depth of the tank?

Solution given is
Let the depth of the tank be h meter
πr²h = 4004
h = 4004/ πr²
h = (4004 x 7/22 x 1/14)
h = 91 m.

I think admin has considered 2r =14 only in place of r^2 ( 7^2).

It should be

Let the depth of the tank be h meter
πr²h = 4004
h = 4004/ πr²
h = (4004 x 7/22 x 1/49)
h = 26 m.
