Answer 2

ANSWER:

20 members are there in the club in order to contribute as many 10 rupees as the number of members to raise the subscription of amount rupees 4000.

EXPLANATION:

Let the required number of persons be x.

Each member contributed as many 10 Rs as the no. of members

Total number of members x

Contribution of each member is 10x

Subscription amount is INR 4000

Therefore,

$10 x * x=10 x^{2}$

$10 \mathrm{x}^{2}=4000$

$\mathrm{X}^{2}=4000 / 10$

$\mathrm{X}^{2}=400$

$\mathrm{X}=\sqrt{400}$

X= 20
