$\begin{array}{cc}\text{1st Member}& \text{₹ 30,000}\\ \text{2nd Member}& \text{₹ 40,000}\\ \text{3rd Member}& \text{₹ 50,000}\\ \text{4th Member}& \text{₹ 60,000}\\ \text{5th Member}& \text{₹ 70,000}\end{array}$

• A. 50000

Answer 1

The correct option is A 50000

The total income of family $=30000+40000+50000+60000+70000=250000$

Average amount of rice = $\frac{\text{Sum of all the observations}}{\text{Number of observations}}$ = $\frac{250000}{5}$ = $₹50000$
