(Assume no death occurred in the family since the birth of the youngest)

A) 19 years B) 16 years
C) 18 years D) 20 years
 
Answer & Explanation Answer: D) 20 years

Explanation:

Present total age of the members = 26(5) = 130 years.

Present total age of the remaining four members = 130 -10 = 120 years

a. Total amount invested in the business in Rs. 22,000.

Explanation:

a and b give, profit after 3 years = Rs.(3/8 x 22000) = Rs.8250.

From c also, profit after 3 years = Rs. (2750 x 3) = Rs. 8250.

∴ P's share = Rs.(8250 x 5/11) = Rs. 3750.

Thus, (either C is redundant) or (a and b are redundant).
