Let the distance between points 'A' and 'B' = d km Then, according to the question, (d/36) - (d/72) = 9 Or {(2d - d)/72} = 9 Or d/72 = 9 So, d = 648 And so, 70% of the distance from 'A' and to 'B' = 648 X 0.7 = 453.6 km Remaining distance = 648 – 453.6 = 194.4 km So, time taken = (453.6 ÷ 63) + (194.6 ÷ 28) = 7.2 + 6.9 = 14.1 hours
{(700 ÷ 20) × 40} – 30 × 18 = ?% of 1000
[4(1/3) + 4(1/4)] × 24 – 62 = ?2
1/6+ 999*53/54 ×9 = ?
30 of 20 - 40 + 182 - 23 × ? = 83
6 × 1.8 × 0.25 × 70 = ? + 9.5
36 x 3.6 ÷ 0.5 ÷ ? = 64
√11025 x √5625 - (50)² = (?) + (73)²
118 × 6 + 13 + 83 = ?
60% of 500 + (729) 1/3 - ? = 72
20% of 10% of 900 + 84/12 = ?2
