Question

A boy spent 2/7 of his pocket money on transport and 1/5 on sweet. if he left with 20. what is the amount of money in the boys pocket​

Answer 1

Answer:

x = 350

Step-by-step explanation:

x - starting amount

$\frac{2}{7} x$  = after transport

$\frac{1}{5} (\frac{2}{7} x)$ = after sweets

$\frac{1}{5} (\frac{2}{7} x)$ = 20

$(\frac{2}{35} x)$ = 20

2x = 700

x = 350
