Question

Ratio of salaries of A and B is 4:6 the ration of savings of A and B is 3:2.If B saves 20% of his salary,ahat preceny of his savings does "A" save?

Answer 1

salaries are 4x,6x
savings are 3y,2y
$6x \times \frac{20}{100} = 2y \\ \\ x = \frac{10y}{6}$
putting value of x in 4x---40y/6

percentage of savings of A is
$\frac{3y}{ \frac{40y}{6} } \times 100 \\ \\ \frac{18y}{40y} \times 100$
A saves 45%
