Question

The number of members of a club is increased by 10% every year. If the initial number of the members is 500, then what will be the number at the beginning of the third year?

पर्याय

• 610

• 615

• 620

• 605

Answer 1

605

Explanation:

No. of Members initially = 500

Increasing Rate = 10% per year

Time = 2 year

No. of people after 2 years ${\displaystyle =\text{P}{[1+\frac{\text{r}}{100}]}^2}$

${\displaystyle \text{A}=500{[1+\frac{10}{100}]}^2=500\times \frac{121}{100}}$

= 605
