. In an examination 70% of student passed in physics, 65% in chemistry. 27% failed in both subject. The percentage of students who passed is :

Answered by admin @ 20/08/2021

Given, 70% students passed in physics.

so, 1 - 70/100

= 30% failed in Physics. -------------- (1).

Given, 65% students passed in Chemistry

So, 1 - 65/100

= 35% failed in Chemistry ---------------- (2).

Percentage of students failed in both subject = 27%. ---------- (3)

On solving (1),(2),(3), we get

= 35 + 30 - 27

= 38%.

Percentage of students passed = 100 - 38%

= 62%.

Hope this helps!
