Answer D Quantity I Time taken by A alone to complete the work 15 days Time taken by B alone to complete the work 12 days Part of work done by A alone in 1 day 115 So, part of work done by A alone in 5 days 515 13 Remaining part of work 23 Time taken by B and C together to complete remaining work 4.8 days So, time taken by B and C together to complete the whole work So, 4.8 32 7.2 days So, time taken by C alone to complete the whole work 18 days Quantity II Let present ages of A and B are 3x and 2x respectively. So, 3x 2x2 2x 2.5 x 5 Present age of A and B are 15 years and 10 years, respectively. Since, average of present ages of A, B, C and D 15 years So, 15 10 C D4 15 C D 35 Since, C is older than D. So, present age of C 18 years. Hence, Quantity I Quantity II

can do it in 12 days. A worked alone for the first 5 days and then left. B and C together finished the remaining work in 4.8 days. How long will it take C to complete the work on his own? Quantity II: The current age ratio of A to B is 3:2, and the average age of A, B, C, and D is 15 years. B’s age is 2.5 years less than the average of A and B’s ages, and C is older than D. What is C’s current age? In each of the following questions, read the given statement and compare the Quantity I and Quantity II on its basis.

A Quantity I > Quantity II

B Quantity I < Quantity II

C Quantity I ≥ Quantity II

D Quantity I ≤ Quantity II

E Quantity I = Quantity II or relation cannot be determined
