Answers :
1). Answer: c)
Diagonal of a cube =√3a
a = 8
Diagonal of a cube =√3 (8)
Diagonal of a cube = 8√3
2). Answer: c)
Speed of Fastest cars = 140 / 5 = 28 kmph
Speed of lowest car = (28*5)/7 = 20 kmph
3). Answer: a)
10 men ——– 30 days
10 men ——— ? Twice the efficiency
10 * 30 = 2 * 10 * x
X = 15 days
4). Answer: b)
2 sin x.cos x = Sin2x
5). Answer: c)
Cosec 90° + sec 60 ° = 1 + 2 = 3
6). Answer: b)
30 A /100 = 50 B/100
A : B = 5 : 3
7). Answer: c
8). Answer: d)
Total age of girls = 20 * 5 = 100
Total age of boys = 22 * 5 = 110
Total Average = Total Age/Total No. of students
= (100 + 110)/ 10 = 210/10 = 21
9). Answer: c)
√440 ≈ √ 441 = 21
√50 ≈ √49 = 7
√440 + √50 ÷7 = 21 + (7 ÷ 7) = 21+1 = 22
10). Answer: d)
344 + 908 + 978 – 867 – 230 – 123
= 2230 – 1220
= 1010 ÷ 4
= 252. 5
