Show answer & explanation
Correct answer: C
Answer: 56%
Let the number of girls = 4x and boys = 6x. Total candidates = 10x.
Degree holders among girls = 50% of 4x = 2x.
Degree holders among boys = 40% of 6x = 2.4x.
Total degree holders = 2x + 2.4x = 4.4x, which is 44% of the total 10x.
Therefore non-degree holders = 100% - 44% = 56%.
Hence the percentage of candidates who are non-degree holders is 56%.
