Answer 1

Answer:

Mr Lal's income = ₹7,875

Step-by-step explanation:

Mr Moti Lal spends 20% of his income on house rent

After house rent expenses, he is left with (100 - 20)% = 80% of is income.

60% of these 80% of his income is spent on house hold expenses.

∴ Mr Lal's savings = (100 - 60)% of 80% of his income.

= 40% of 80% of his income

= $\frac{40}{100}$ of $\frac{80}{100}$ of his income = ₹2520 [This information is given]

=> $\frac{8}{25}$ of his income = ₹2520

∴ Mr Lal's income = ₹2520 x $\frac{25}{8}$ = ₹315 x 25 = ₹7,875
