The number of girls appearing for an admission test is twice the number of boys. If 30% of the girls and 45% of the boys get admission, the percentage of candidates who do not get admission is:
Explanation:
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 = 1.05b2b+b×100% = 35%
∴ 65% of the candidates do not get admission.
Hence, option (d).
