In an examination, 950 boys and 250 girls appeared. 90 % of the boys and 60 % of the girl passed the examination. The percentage of candidates failed is?
Correct Answer: 16.25%
Explanation:
Number of failures = 10% of 950 + 40% of 250
= (10/100) x 950 + (40/100) x 250 = (95 + 100) = 195
Fail percentage = [195/(950 + 250)] x 100
= (195/1200) x 100 = 16.25%
