Ram can finish a puzzle in 3 hours and Shyam can do the same in 2 hours. Both of them finish the puzzle and get 15 candies. What is Ram’s share?
Answer: B
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
