A group of students decided to collect as many paise from each member of group as is the number of members. If the total collection amounts to Rs. 59.29, the number of the member is the group is:
A. 57
B. 67
C. 77
D. 87
C?
It would help if you proofread your questions before you posted them. "paise"? "Rs"? Which member?
If there are n members, you collect n^2.
√59.29 = 7.7
Looks like Rs1 = 100paise.
√5929 = 77
Us ferriners don't always understand other currencies.
To solve this problem, we can use algebraic equations.
Let's assume that the number of members in the group is 'x'. According to the given information, each member is contributing 'x' paise.
The total collection from all the members can be calculated by multiplying the number of members (x) with the contribution per member (x paise):
Total collection = x * x paise = x^2 paise
The total collection is given as Rs. 59.29. Since 1 Rupee consists of 100 paise, we need to convert the total collection amount to paise:
Total collection in paise = 59.29 * 100 = 5929 paise
Now we have an equation:
x^2 paise = 5929 paise
To find the value of 'x', we need to take the square root of both sides of the equation:
√(x^2 paise) = √(5929 paise)
x = √(5929) [taking square root on both sides]
By calculating the square root of 5929, we get:
x = 77
Therefore, the number of members in the group is 77.
So the correct option is C. 77.
