Question

Arun spent 1/10 of his salary to pay the rent of his house ,2/5 of his salary on the repair of his car and another $ 15000 from his salary for the school fees of his children. He also spent $ 21000 on some other items and he was left with $ 13000 . Find his salary.

Answer 1

Answer:

$98000

Step-by-step explanation:

Salary of Arun = x

Then, according to question

House rent = x/10

Car repair = 2x/5

School fees = $15000

Other items = $21000

Left amount = $13000

Total of all the above mentioned amounts is equal to Arun's salary

So,

x = x/10 + 2x/5 + $15000 + $21000 + $13000

x = x/10 + 4x/10 + $49000

x = 5x/10 + $49000

x = x/2 + $49000

x - x/2 = $49000

2x/2 - x/2 = $49000

x/2 = $49000

x = 2 × $49000

x = $98000
