Question

A&B together have Rs 1210. If 4/15 of A's ammount is equal to2/5 of B's ammount, how much ammount does B have?

Answer 1

hi dillip ,

Given
A&B together have Rs 1210
a+b = 1210

4/15 of A's amount is equal to2/5 of B's amount
4/15 a = 2/5 b
4a = 2/5 * 15 * b
4a = 6b
a = 3/2b

substituting 'a' value
a+b = 1210
3/2b + b = 1210
5/2b = 1210
5b = 2420
b = 484

also
a=3/2b = 726

so B has Rs 484

Hope it helped
