If one-sixth of one-third of a number is 10, then what is one-fifth of the number?

Question: If one-sixth of one-third of a number is 10, then what is one-fifth of the number?

Solution:
Let, the number is x,

ATQ,
⇒ (1/6) × (1/3) × x = 10
⇒ x /18 = 10
⇒ x = 10 × 18
∴ x = 180

Now, find one-fifth of the number is,
x/5 = 180/5 = 36

So, one-fifth of the number is 36.
