These questions are based on following graphs. Classification of appeared candidates in a competitive test from different States and qualified candidates from those States.
What is the ratio between number of candidates qualified from States B and D together and the number of candidates appeared from State ‘C’ respectively ?
Number of candidates qualified from State B = $$\frac{16}{100} \times 9000$$ = 1440
Number of candidates qualified from State D = $$\frac{21}{100} \times 9000$$ = 1890
=> Total number of candidates qualified from state B and D = 1440 + 1890 = 3330
Number of candidates appeared from State ‘C’ = $$\frac{8}{100} \times 45000$$ = 3600
=> Required ratio = 3330 : 3600
= 37 : 40
