Answers with Explanation !!!!!!
1.(4) No. of boys in school R & U together
= (2000 * 72.5)/100 + (1000 * 82.5)/100 = 1450 + 825 = 2275
Required % = 2275/3000 * 100 = 75.83
2.(3)
3.(1)
4.(2) Required average = ½ {(2500 * 60)/100 + (3000 * 55)/100} = 1575
5.(3) 40% of 2500 : 45% of 3000
6.(2)
7.(2) (24/16)*100=150%
8.(5) (11-7)% of 7390= 296 (approx )
9.(3)
Science = (25780 * 28)/100 - (7390 * 32)/100 = 4853 appr.
Engineering = (25780 * 16)/100- (7390 * 11)/100 =4124 – 813 = 3311 appr.
Commerce = (25780 * 18)/100- (7390 * 16)/100 = 4690 – 1182 = 3458 Approx
10.(1) (16+7)% of 7390 = 1700
