as many paise from each member of the
group as is the number of members. if the
total collection amounts to rupees 22.099
the number of members in the group is?​

Answer 1

Solution:

Let the total number of members = x

So, money collected from each member = x paise=Rs. 0.01x

Total money collected = x×0.01x=0.01 x²

⇒0.01 x² =22.09

⇒x²= 22.09/0.01

=>x²=2209

⇒x²=47×47

=>x=47

So, there are 47 members in the group.

Answer 2

Answer:

money collected = ( 22.09×100) paise =2290 paise

number of members = √2290=47
