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
MY ANSWER IS 45 MINUTES.....(3/4 HR)
IS IT CORRECT ?????????????
one hour
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.
yes,3/4 hour is right answer
K. Can you tell me logic behind telling "One hour" before???
my answer is also 45 minutes
is it correct or not ?
