Present age of monu is 27 years. Given 5 years ago..ratio of monu's age to ninu's age was 11:7
So 27-5 = 22 ...
22 is multiple of 11
( y 11 means monu's part is 11 and ninu's part is 7 . We are calculating monu's present age so we should take 11)
As 22 is multiple of 11 .condition satisfied. ..
Hence from options.. 19 years is the correct answer
