Question 123
Number of candidates passing in the exam from City F is what per cent of the total number of candidates appearing from all the cities together ? (rounded off the two digits after the decimal)
Solution
Number of candidates appearing from F = 2.73 lakhs
Ratio of Pass: Fail = 7:5
Number of pass = $$ \frac{7}{7+5}$$*2.73 = 1.59 lakhs
Total number of candidates from all the cities = 1.25 + 3.14 + 1.08 + 2.27 + 1.85+ 2.73 = 12.32 lakhs
The required percentage = 100 * 1.59/12.32 = 12.91%
