Question

One-fourth of one-third of two-fifth of a number is 15. What will be 40% of that
number?
​

Answer 1

Answer:

180

Explanation:

Let the number be x

By question,

$\frac{1}{4}X \frac{1}{3}X\frac{2}{5} x = 15\\\\\frac{2}{60} x = 15\\x = 15X30 = 450$

The number is 450.

40% of 450 is $0.4 X450 = 180$
