G ? 9/20 x 48/100 x 7/100 x 300000 = 4536
Hence, State C and G have equal number of qualified male candidates
Correct Answer: 4536
Explanation:
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
Correct Answer: 83

Correct Answer: 864
Explanation:
The total number of students in Stitching and Drama Classes= ( % of students enrolled in Stitching + % of students enrolled in Drama classes) x 100/ Total number of students in all classes
Required number of students = (11 + 13) x 3600 / 100 = 24 x 36 = 864
Correct Answer: 3 : 1
Explanation:
Required ratio = ( % of students enrolled in Singing + % of students enrolled in Dancing classes)/% of students enrolled in Drama Classes
Required ratio = (18 + 21) : 13 = 39 : 13 = 3 : 1

= 12250 + 13176 = 25426
