How much time a train 120 metres long running at the speed of 36 km/hr will take to cross a bridge 130 metres in length?
Distance = (Length of the train + length of the bridge) = 120 + 130 = 250 m Speed of Train = 36 km/hr = 36× 5/18 = 10 m/sec. Time = Distance / Speed = 250/10 = 25 sec.
√10201 × √3969 - (52)² = √? + (60)²
...1090 + 237 + 30549 - 86 - 104 = ? x 6
4567.89 - 567.89 - 678.89 = ?
(? × 3)2 - 85 = 115 × 5 + 69
181/8 + 51/4 – 63/8 = ? + 9/2
26 2 – 13% of 400 + (529 ÷ 23 2 ) = ? 2
(750 / 15 × 15 + 152 + 20% of 125) = ?3
(1748 ÷ 8) + 76.8 × 35 =(? × 4) + (42 × 35.5)
((12+12+12+12)÷4)/((8+8+8+8+8+8)÷16) = ?
