? * 16 = (3240/30) * 15
? * 16 = 3240/2
? = 101(approx)
2) Answer: b)
61% of 985 – 151.046 =? – 63% of 698
60/100 * 985 – 151 =? – 63/100 * 700
591 – 151 =? – 441
? = 881 = 880 (Approx.)
3) Answer: d)
? = (448/32) * (779/19) * (228/76)
? = 14 + 41 + 3
? = 58
4) Answer: a)
1234.67 + 657.009 + 89.763 + 452.987 + 6753.099 =?
1235 + 657 + 90 + 453 + 6753 =?
9188 =?
5) Answer: c)
√7398 * √11025 + √627 =? – √731
√7396 * √11025 + √625 =? – √729
86 * 105 + 25 =? – 27
9030 + 25 + 27 =?
9082 =?
Directions (6 – 10):
Total students = 450
No of boys = 450/9 * 5 =250
No of girls = 450/9 * 4= 200
No of girls participated in Singing = 200*20/100 = 40
No of girls participated in dance = 160 * 2/8 = 40
No of girls participated in drama = 160 * 3/8 = 60
No of girls participated in speech = 160 * 3/8 = 60
No of boys participated in drama = 250 * 2/5 = 100
No of boys participated in singing = 150 * 2/5 = 60
No of boys participated in dance = 150 * 3/5 = 90
