Question 142

What is the percentage of candidates have qualified from state ‘A’ and ‘C’ together, rounded off to two decimal points ?

Solution

Number of candidates appearing from A = .15 * 3,00,000 = 45,000

Number of candidates appearing from C= .06 * 3,00,000 = 18,000

Number of candidates qualified from A = 45,000 * .49 = 22050

Number of candidates qualified from C = 18,000 * .54 = 9720

% age qualified from A and C = $$\frac{Total. qualified}{Total.appeared}$$* 100 = $$\frac{22050+9720}{45,000+18000}$$* 100 = 50.43%
