Question

expenditure and saves the rest. If he saves 1890 per month, what is his total income?​

Answer 1

Answer:

here is ur answer

Step-by-step explanation:

let's assume that he receives an income of ₹x per month

Step-by-step explanation:

25% of x would be x/4

and 90% of x/4 would be 9x/40

if we subract the total expenditure from his incom i.e. x we get

x - \frac{x}{4} - \frac{9x}{40} = 1890x−

4

x

−

40

9x

=1890

if we solve the following equation We get x=3600

Answer 2

Step-by-step explanation:

Let total income be x

According to question:

He spend 25% of total on rent = 25/100 * x = x/4

Remaining money = x - x/4

= 3x/4

He spend 90% of remaining on other expenditure

= 90/100 * 3x/4 = 27x/40

Remaining money = 3x/4 - 27x/40

= 3x/40

But he saves remaining money and his saving is 1890. So,

3x/40 = 1890

x = (1890 * 40)/3

x = 630 * 40

x = 25200

Hence his total income is 25200
