Question
Average speed of ‘A’ during a 24-hour journey is 38
km/h. If he covered the first 120 km of his journey at a speed of 20 km/h, then find the speed at which ‘A’ travelled during the remaining journey.Solution
Total distance covered by ‘A’ = 24 × 38 = 912 km Time taken to cover 120 km = 120/20 = 6 hours Time taken to cover remaining distance = 24 – 6 = 18 hours So, required speed = {(912 – 120)/18} = 44 km/h
1199.98 ÷ 40.48 × 20.12 = ? × 3.16
Direction: Please solve the following expression and choose the closest option
40.024 of 54.89% of 19.9 = ? × √(2661.98/22.09)

2380.03 ÷ 84.98 x 39.9 = ? + 15.32
15.232 + 39.98% of 539.99 = ? × 6.99
(100.01% of 44.89) ÷ 14.98 = √? - √48.98
20.22 × 11.99 + 140.15 = ?
What approximate value should replace the question mark?
12.45% of 640.20 − 60% of 2500 = ? − 9000.10
