Question

In an examination, there were 2000 candidates of which 900 candidates were boys and rest were girls. If 32% of the boys 38% of the girls passes then the total percentage of failed candidates is

• A. 35.3%
• B. 64.7%
• C. 68.5%
• D. 70%

Answer 1

The correct option is B 64.7%

Boys = 900, Girls = 1100
Passed = (32% of 900) + (38% of 1100)
= 288 + 418 = 706
Failed = 2000 - 706 = 1294

Failed % =
$(\frac{1294}{2000}\times 100)=64.7\%$
