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

x = 350

Explanation:

x - starting amount

`(2)/(7) x` = after transport

`(1)/(5) ((2)/(7) x)` = after sweets

`(1)/(5) ((2)/(7) x)` = 20

`((2)/(35) x)` = 20

2x = 700

x = 350
