Question
A train takes 46 seconds to cross the 214 m long bridge.
If the same train takes 23 seconds to cross a signal board, tell the length of the train. (In meters)Solution
Let the length of the train be x m. Length of the platform = 214 m As we know, Speed = Distance/time (x+214)/46 = x/23 x + 214 = 2x x = 214 Length of the train is 214 m.
The value of 43-3× (4×6+12/3 ×6-4×5) +4?
13 X ? = 85 X 4 + √81 + 2

What will come in the place of question mark (?) in the given expression?Â
48 ÷ 4 × (3 + 5) – 6² + 10 = ?
5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630
72% of 486 – 64% of 261 = ?
20% of 450 - 15% of 400 = 25% of ?
56 × 18 + ? × 21 – 49 × 12 = 63 × 26Â
Simplify the following expressions and choose the correct option.
[(2/3 of 270) ÷ 9] + [(5/6 of 96) ÷ 8] = ?
(21 X 5) + ? = (480 - 120) ÷ 3
