Answer 2

Answer

$⟹ \frac{x}{72} = \frac{25}{100} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ ⟹x \times 100 = 72 \times 25 \\ ⟹x = \frac{72 \times 25}{100} \: \: \: \: \: \: \: \: \: \: \: \\ ⟹x = \frac{1800}{100} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ ⟹x = 18 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

Now, 18 students are good in maths

.

Now, we find the how many

students are not good.

.

$⟹25 - 18 \\ ⟹7 \: \: \: \: \: \: \: \: \: \: \: \:$

Hence the 7 students are not

good in maths.
