Answer 2

Answer:

Suppose Anil's pocket money was ₹x

$He \: spent \: \frac{2}{5} \: of \: x = \frac{2}{5} \times ₹x = ₹ \frac{2x}{5} \\ \\ money \: left \: with \: him \: = ₹x - ₹ \frac{2x}{5}$

$₹180 = ₹( x \times \frac{2x}{5} ) \\ \\ 180 = \frac{5x - 2x}{5} = \frac{3x}{5} \\ x = \frac{180 \times 5}{3} = 300$

Hence, Anil received ₹300 as pocket money
