Answer 2

Question

If Kamla is 4 times as old as her son. 5 years ago her son was 1/7 of her age. What is Kamla's age now?

Solution

Let, age of Kamala's son be x

age of Kamala be 4x

Five years ago, age of Kamala be 4x-5

Five years ago, age of Kamala's son be ⅐(4x-5)

ATP

$\frac{1}{7}(4x - 5) = x - 5 \\ = ) \: \frac{4x}{7} - \frac{5}{7} = x - 5 \\ = ) \: 5 - \frac{5}{7} = x - \frac{4x}{7} \\ = ) \: \frac{35 - 5}{7} = \frac{7x - 4x}{7} \\ = ) \: \frac{30}{7} = \frac{3x}{7} \\ = ) \: \frac{30}{7} \times \frac{7}{3} = x \\ = ) \: 10 = x$

Ans:- Kamala's age now = (4×10)yrs = 40yrs

Her son's age now = 10yrs
