Solutions:
6). Scientist = 100 – Others = 100 – 75 = 25%
Required Percentage = (25/11)*100 = 227%

7). % of People in Architect = x ; % of People in Scientist = 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

8). Ratio = 22*75/ 14*20 = 165:28

9). [12*55 + 25*75]/[12*45 + 25*25] 507 : 233

10). [12000*16*50/12000*14*20]*100 = 286
