Answer 2

Answer:

If 300 students are studying English, Maths or both. 60 percent of the students are studying English and 70 percent are studying Maths then 90 students are studying both​.

Step-by-step explanation:

Total number of students =300

Number of students studying English 60% of 300= $\frac{60}{100} \times 300 = 180$

Number of students studying Maths 70% of 300=  $\frac{70}{100} \times 300 = 210$

Therefore, the  total number of students studying both subjects

= 180+210−300

= 390 -300

= 90 student

So, 90 student are studying both​.
