Number of candidates appeared from State G = Total number of candidates x % of appeared students from state G.
Number of candidates qualified from State G = Number of candidates appeared from State G x % qualified from state G
Number of male candidates qualified from State G = Number of candidates qualified from State G x Ratio of male qualified / total RatioCorrect Option: A
Number of candidates appeared from State G = Total number of candidates x % of appeared students from state G.
Number of candidates appeared from State G = 3,00,000 x 7/100
Number of candidates qualified from State G = Number of candidates appeared from State G x % qualified from state G
Number of candidates qualified from State G = 3,00,000 x 7/100 x 48/100
Number of candidates qualified from State G = 30 x 7 x 48 = 10080
Number of male candidates qualified from State G = Number of candidates qualified from State G x Ratio of male qualified / total Ratio
Number of male candidates qualified from State G = 10080 x 9 /(9 + 11) = 10080 x 9/20 = 4536
