Hi Friends!!! Myself studying at IIM Bangalore, pursuing my EGMP. I am fond of Maths and solving them in such a platform makes our minds to think and never stop thinking and feels us to be young and back in school.

So I want to solve and discuss any topics that you might have faced or fear to face during interviews, GDs, Problem Solving, Witty solutions during Interview etc.
Hope the learning would be great!!!

Suppose present ages of x and y are X and Y respectively.
when x was Y years old [( X-Y) years earlier), y was [Y-(X-Y)] i.e. 2Y-X years old.

As per goven statement, X= 5(2Y-X)
Then 6X=10Y
X/Y = 10/6 = 5/3
