Explanation:

Explanation :
% of People in Engineering = x ; % of People in Teaching = y
x + y = 100% -59% = 41%
x + y = 41
y – x = 9 => y = 25 ; x = 16
Total number of Males = 12000*(12*55 + 16*50 + 11*65 + 25*25 + 22*75 + 14*80) / 100 * 100 = 6684
Total number of Females = 12000 – 6684 = 5316
Difference = 6684 – 5316 = 1368
