Answer:
Total number of candidates = 6000
60% of the candidates were boys
12% of the girls failed
14% of the boys failed
start by finding the number of boys and girls:
Number of boys = 60% of 6000 = 3600
Number of girls = 40% of 6000 = 2400
Next, find the number of boys and girls who passed the examination:
Number of boys who passed = 86% of 3600 = 3096
Number of girls who passed = 88% of 2400 = 2112
Total number of successful candidates = 3096 + 2112 = 5208
The percentage of successful candidates = (5208/6000) x 100% = 86.8%
the answers are:
a. The number of successful candidates is 5208.
b. The percentage of successful candidates is 86.8%.
