Question

ravi spends 30% of his salary on house rent and 60% on house expenditure if he saves 6300 find his total salary

Answer 1

let the total salary be X
60/100x = expenditure
30/100x = house rent
total salary-(expenditure+salary)=saving
x-(90/100x)=6300
10/100x =6300
X=(6300*100)/10
X=630000/10
X=63000

Answer 2

Let the total salary be Rs X.

X = 100%

Rent = 30%
Expenditure = 60%

Saving = [100-(60+30)]%
= (100-90)%
= 10%.

Saving = 10% of Rs X.
Rs 6300 = 10/100 * X.
Rs 6300 = X/10.
X = 10*6300
X = Rs 63000.
