$\frac{60}{100} x = 90$

$x = 90 \times \frac{100}{60}$

$x = 150$

Answer 2

Answer :

We have,

• 60% of a number is 90.

To do,

• What will be the $\dfrac{4}{5}$ of the number ?

Solution :

Let us first find the number,

• Let the number be x

According to the questuon

= 60% × x = 90

= $\dfrac{60}{100}$ × x = 90

= x = $\cancel{90}$ × $\dfrac{100}{\cancel60}$

= x = 1.5 × 100

= x = 150

Now,

• Let us solve the required answer of thus question which is asked.

= $\dfrac{4}{\cancel{5}}$ × $\cancel{150}$

= 4 × 30

= 120.

Thank you !! :D
