K. i put one more and interesting one.

A Lawyer can solve 32 math riddles per hour, and his friend Sam takes three hours to solve the same number. If they both work on them, how long will it take for them to solve 32 math riddles?

Think before answering....

TOTAL RIDDLES SOLVED IN 1 HR - 32+32/3 =128/3

TIME TAKEN TO SOLVE 1 RIDDLE = 3/128 HR

TIME TAKEN TO SOLVE 32 RIDDLE = 3/128*32

Ans is 3/4 hours, or say 45 minutes.What Shikha said! Those who say 1 hour, i think they are wrong.See, if one friend can solve 32 riddles in one hour ,and if someone also joins him then they together can solve it in less than 1 hr.
