Answer & solution
- A
35
- B
50
- C
60
65
Solution
Let the number of boys appearing for the admission test be b.
Number of girs appearing for the admission test = 2b.
Total boys who got admission = 45% of b = 0.45b
Total girls who got admission = 30% of 2b = 0.6b
Total students who got admission = 0.45b + 0.6b = 1.05b
∴ Percentage of candidates who get admission = = 35%
∴ 65% of the candidates do not get admission.
Hence, option (d).
