Show Answer
Answer:
Correct Answer; A
Solution:
- (a) No. of candidates appeared from, State C = $\frac{8}{100}\times 45000 $ = 3600 State E = $\frac{9}{100}\times 45000 $ = 4050 State A = $\frac{15}{100}\times 45000 $ = 6750 State F = $\frac{18}{100}\times 45000 $ = 8100 $\therefore $ Required ratio = $\frac{3600 +4050}{6750 +8100} $ = $\frac{7650}{14850} $ = 17:33
