${\bold\pink{⇝}}$180 students are studying English

⠀

➥ Students studying Maths = 70%

${\bold\blue{⇒}}$ 70% of 300

$\frac{70}{100} \times 300$

${\bold\pink{⇝}}$210 students are studying Maths.

⠀

${\bold\green{Now,}}$

${\bold\blue{⇒}}$ Students studying both English and Maths = students studying maths + students studying English - students studying English, maths or both

${\bold\pink{⇝}}$ (210 + 180) - 300 = 90
