Question
A train 180 meters long is moving at a speed of 72 km/h.
How long will it take to cross a platform 120 meters long?Solution
Speed of the train = 72 km/h = (72 × 1000) / 3600 = 20 m/s. The total distance to be covered = Length of the train + Length of the platform = 180 + 120 = 300 meters. Time = Distance / Speed = 300 / 20 = 15 seconds. Thus, the train will take 15 seconds to cross the platform. Correct option: d
239.977 ÷ 5.998 + √840.913 × 6.113 = ? + 117.948
? 2 + (39.99 × 10.99 + 7.01) - (39.99 × 2.99 2 + 21.99) = 21.99 × 23.01
(10.013 – 12.04) = ? + 7.98% of 4999.98
7.9% of 174.92 + 24.99 - 131.99 ÷ 11.95 × 2.98 = ?
1111.25 × 9.05 + 2323.23 × 9.05 – 2121.37 × 9.05 = ?
[34.01 × 18.98 – 12 × √576.03 – 198] ÷ 3.95 = ?
³√? `xx` 32.87 + 59.83 `xx` 28.7665 – 48.8745 `xx` 21.642 = 1085.344
25.11% of 199.99 + √143.97 ÷ 6.02 = ?
115.98 + 109.01 + (√575 - 17) X 20.09 - 204.89 + 38.03 = ?
(33.95)2 – (25.004)2 + (18.0099)2 – (9.07)2 = ? - (14.990)2
