Answer 2

Answer:

$x = 80$

Step-by-step explanation:

let us take his pocket money as x

he has spent 3/4th of his pocket money

$i.e \: \: \frac{3}{4} x$

$i.e \: \: x - \frac{3}{4} x$

Remaining money will be pocket money less the money spent is 20

$i.e \: \: x - \frac{3}{4} x = 20$

if you take the LCM

$\frac{4x - 3x}{4} = 20 \\ \frac{x}{4} = 20 \\ x = 80$

here is the solution you may understand it.
