Question

If one third of one fourth of a number is 15, then three tenth of that number is:
1. 35
2. 36
3. 45
4. 54

Answer 1

Correct Answer - Option 4 : 54

Given:

One-third of one-fourth of a number = 15

Calculation:

Let the number is n

Then, 

⇒ 1/3 × 1/4 × n = 15

⇒ n/12 = 15

⇒ n = 12 × 15

⇒ n = 180

Now, 

Put the value of n = 180 then,

Three-tenth of that number will be = (3/10)n

⇒ 3/10 × 180

⇒ 54

∴ Three-tenth of that number is 54
