Answer 2

Step-by-step explanation:

Given :-

A boy after spending 2/8 of his money has Rs. 30 left.

To find :-

How much money did he have in the beginning ?

Solution :-

Let the money the boy has in the beginning be Rs. X

Money spent by him = 2/8 of his money

=> (2/8)of Rs. X

=> (2/8)×X

=> (2×X)/8

=> 2X/8

=> X/4

Money spent by him = Rs. X/4

Remaining money at him

= Total money - money spent

= X-(X/4)

= (4X-X)/4

= 3X/4

Remaining money = Rs. 3X/4

According to the given problem

Remaining money at him = Rs. 30

=> 3X/4 = 30

=> 3X = 30×4

=> 3X = 120

=> X = 120/3

=> X = 40

The required money = Rs. 40

Answer:-

The money the boy has in the beginning is Rs. 40

Check:-

Money at the beginning =Rs. 40

Money spent = 2/8 of Rs. 40

=> (2/8)×40

=>(2×40)/8

=> 80/8

=> 10

Remaining money = 40-10 = Rs. 30
