Question

explain this sum please?

Answer 1

Let the man s income is X

Money spend on food = 2X/5

Remain= X-2X/5= 3X/5

Money Spend on Clothing = 3X/5 ×4/5= 12X/25

Remain = 3X/5 -12X/25 = 3X/25

According to Question

3X/25 =600

X= 5000

So his income is Rs. 5000.

Answer 2

Answer

Let the total income be = x

Spend on food = $\dfrac{2x}{5}$

Remaining = $x - \dfrac{2x}{5}$
= $\dfrac{3x}{5}$

Spend on clothing = $\dfrac{3x}{5} × {4}{5}$
= $\dfrac{12}{25}$

Remaining = $\dfrac {3x}{5}$ - $\dfrac {12x}{25}$
= $\dfrac{3x}{25}$

Given, Remaining = 600

Hence,

600 = $\dfrac {3x}{25}$

600 × 25 = 3x

15000 = 3x

x = 5000

Hence total income is ₹5000
