Rohan is asked to figure out the marks scored by Sunil in three different subjects with the help of
certain clues. He is told that the product of the marks obtained by Sunil is 72 and the sum of the
marks obtained by Sunil is equal to the Rohan’s current age (in completed years). Rohan could not
answer the question with this information. When he was also told that Sunil got the highest marks
in Physics among the three subjects, he immediately answered the question correctly. What is the
sum of the marks scored by Sunil in the two subjects other than Physics?
(a) 6 (b) 8 (c) 10 (d) Cannot be determined
well... the fact here is to realise that the sum has to be a value that is got by two or more combos
ReplyDeletein this case..that sum is 14
we can get 14 by 2,6,6 or 3,3,8 both which add up to 14 and multp give 72
now since when said hieghest in phy...means its the case of 3,3,8 and hence sum of the other two comes out as 6
hence option (a)
by the way...its firday today right... lemme check my calender.... O.o
ReplyDeleteYeah, I made a technical error. While scheduling the post :) Sorry but it can't be fixed now!! :D
ReplyDeleteOption A
ReplyDeletesum=rohan's age
still he is not able to find the variables
=> he got atleast 2 values having same sum
Now it is easy to solve
