Fast Fraction Aptitude Problem

The Fast Fraction Aptitude Problem is as follows :)

If one-fourth of one-third of a number is 15, then three-tenths of that number is ? 

a). 35 

b).36

c).45

d).54

The solution is given below :

EXPLANATION :

Say the number is “y”

So then one-fourth of one-third of that number will be (1/4) X (1/3) X y = (y/12)

But given that  (y/12) = 15.

This implies that y = 12 X 15 = 180.

Now three-tenths of that number will be (3/10) X 180 = 54 :)

Hence the answer is (d) 54
