d) 252.5

Diagonal of a cube =√3a

a = 8

Diagonal of a cube =√3 (8)

Diagonal of a cube = 8√3

Speed of Fastest cars = 140 / 5 = 28 kmph

Speed of lowest car = (28*5)/7 = 20 kmph

10 men ——– 30 days

10 men ———  ?        Twice the efficiency

10 * 30 = 2 * 10 * x

X = 15 days

2 sin x.cos x = Sin2x

Cosec 90° + sec 60 ° = 1 + 2 = 3

30 A /100 = 50 B/100

A : B = 5 : 3 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

√440 ≈ √ 441 = 21

√50 ≈ √49 = 7

√440 + √50 ÷7 = 21 + (7 ÷ 7) = 21+1 = 22
