Question

A man spends 60% of his income and saves rupees 3000 .find his income and expenditure amount.​

Answer 1

Given,

A man spends $60$% of his income and saves ₹$3000$.

Let $x$ be the total income

Savings $= 100$%$-60$%

$3000=40$% of $x$

$3000=\frac{40}{100}\times x$

$x=3000\times \frac{100}{40}$

$x= 7500$

Expenditure $= 60$% of $7500$

$= \frac{60}{100}\times 7500$

$= 4500$

Therefore, his income amount is ₹$7500$ and expenditure amount is ₹$4500$.

Answer 2

Answer:

Let his income be x

% of savings = 100-60= 40%

So 40% of x = 3000

40/100 * x = 3000

x = 3000 * 100 / 40

x = ₹7500

So his income ₹7500

Hence his expenditure = 7500-3000 =₹4500.
