Question

Out of his total income Kumar spends 25% on house rent and 80% of the remaining on other expenditure and saves the rest. If he saves rs 1890 per month what is his total income?

Answer 1

Answer:

12,600

Step-by-step explanation:

Let salary be x

Kumar spends 0.25x on house rent

And in the remaining 0.75x, he spends 80% i.e., 0.8*0.75x = 0.6x on other expenditure.

Savings = x - (0.25x + 0.6x) = 0.15x

Given savings = 1890

x = 12,600

Kumar's income per month is 12,600 rupees

Answer 2

Solution:–

Suppose the total income of Kumar = ₹100

Expenditure on house rent = 25% of 100 = ₹ 25

.°. Amount left = ₹(100 – 25) = ₹75

.

Other expenditure = 80% of ₹75 = $(\dfrac{80}{100}\:×\:75)\:=\:₹60$

Saving = ₹(75 – 60) = ₹15

Now, if saving is ₹15, then total income = ₹100

.°. if saving is₹1, then income = $₹ \dfrac{100}{15}$

.

Or if saving is₹1890, then income = $₹ \dfrac{100}{15}\:×\:1890 \\ \\ = ₹12,600$

Therefore, the total income of Kumar is ₹12,600.
