**b.** 6

**c.** 11

**d.** 12

**ANSWER: 6**

The question is based on efficiency to do work.

Ram can finish a puzzle in 3 hours. Shyam can finish the puzzle in 2 hours.

=>In one hour Ram can finish 1/3rd of a puzzle

=>In one hour Shyam can finish half the puzzle

A total of 15 candies are to be shared amongst both of them

Hence Ram’s share must be = ((Work done by Ram in 1 hour)/(Work done by Shyam in one hour)+(Work done by Ram in hour))*15

=> 1/3/((1/2)+(1/3))*15

=> (1/3/(5/6))*15

=> 6/15*(15)

=>6 candies
