### 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**
