Question

In an examination, $35\%$ of the total students failed in Hindi, $45\%$ failed in English and $20\%$ failed in both. The percentage of those who passed in both the subjects is

• A. $20$
• B. $30$
• C. $80$
• D. $40$

Answer 1

Answer: (D)

Given $35\%$ student failed in Hindi and $45\%$ failed in English and 20% failed in Hindi and English.

Then student failed in Hindi $=35-20=15\%$

And student failed in English $=45-20=25\%$

And $20\%$ failed in both.

So, $15\%$ in English and $25\%$ in Hindi which means that total student failed $=15+25+20=60\%$

Then passed in both subjects students $=100-60=40\%$.
