Question
A train 'B' speeding with 100 kmph crosses another train
C, running in the same direction, in 2 mins. If the length of the train B and C be 150m and 250m respectively, what is the speed of the train C (in km/ph) ?Solution
Given, speed of train B = 100 km/ph Let speed of train C = x km/ph length of train B = 150 m = 0.15 km length of train C = 250 m = 0.25 km time taken = 2 minutes = 2/60 = 1/30 time taken = (length train A + length train B)/( difference i n speed) = 0.4 / (100−x) 1/30 = 0.4 / (100−x) 100 − x = 0.4 × 30 100 − 12 = x X (speed of the train C) = 88 km/ph
(√845 ×19.932+ √4230 ×14.385)/(√1765 ×4.877 ) = ?
{(√2305) % of 74.69} × 15.21 - 27.89 × 44.88 + 45.12% of 2399.87
The greatest number that will divide 398,436, and 542 leaving 7, 11, and 15 as remainders, respectively, is:
2470.03 ÷ 64.98 x 39.9 = ? + 20.32
(1709.87 ÷ 38.09) + (768.11 ÷ 23.87) + (6599.81 ÷ 88.06) = ?
