Question

62. If 3/5 of 60% of a Number is 36, then
the value of the number is :
(1) 60
(27 100
(3) 120
(4) 150​

Answer 1

The mathematical problem is solved below :

It is given that,

$\frac{3}{5} of \: 60\% \: of \: a \: number \: = \: 36$

Let,

The number be x

Here 'of' word can be replaced by x (multiply) sign. It is because the word 'of' denotes multiplication in mathematics.

So according to question, it will be,

$\frac{3}{5} \times 60\% \times x = 36$

Now,

$60\% = \frac{60}{100}$

So,

$\frac{3}{5} \times \frac{60}{100} \times x = 36$

$\frac{3}{5} \times \frac{3}{5} \times x = 36$

$\frac{9x}{25} = 36$

Cross multiplying the terms, we get,

$9x = 25 \times 36$

$9x = 900$

$x = \frac{900}{9}$

$x = 100$

So, the value of x is 100

So, the correct option or the right choice is (2)
