A + B = 1210.
Now find the value of B?
4/15 A = 2/5 B.
A = (2/5 * 15/4) B.
==> A = (3/2) B.
ratio is A : B = 3:2 ==> ratio of A is 3 and ratio of B is 2.
A + B = 1210 // this formula Apply the A value,
(3/2) B + B = 1210 // ratio of B is 2 so B is replace 2.
(3)B + 2 = 1210 * 2,
(3)B + 2 = 2420,
5(B) = 2420,
B = 2420/5,
B = 484.

How will you find B's share directly to 1210?

A+B Total value is R.s 1210.
So Directly we can Calculate B share,
Acc to the question B share 2/5,
Thus 1210 of 2/3,
= 1210 * 2/3,
= 484 RS.

Can you give solution for this problem?
A vessel of 125 lts. Capacity is full of pure milk on the first day 2/5 of the milk is drawn and filled with water, on the second day 2/5 of the mixture is drawn and filled with water, and again the same thing is done on the third day. Find the quantity of milk at the end?
