Question

Dravid parents are in the ratio 17/18:19/17 . if his father of earns rupees 2385 more than his mother how much does each of Dravid parents earns

Answer 1

ratio of their parents earning is 17/18 : 19/17
making the denominators equal
17*17/18*17 : 19*18/17*18
value doesn't change if we multiply numerator and denominator with same number.

289/306 : 342/306
father earns more than mother
so this is the ratio of mother's earning : father's earnings
so the father's earning will be 342x
mother's earnings will be 289x

342x - 289x = 2385
x = 45
so Dravid father's earning = 342x = 15390rs
Dravid mother's earnings = 289x = 13005rs
