Question
A train starting from rest with a uniform acceleration
attains a speed of 108 km/h in 5 minutes. The distance covered by the train in attaining the speed isSolution
Distance = speed × time = 108 × 5/60 = 9 km Therefore, distance in meter = 9 × 1000 = 9000 m
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
19.89% of 449.67 + 14.67% of 299.89 - 9.89% of 99.79 = ?
(13.13 ×  32.98) + 20.15% of 649.99 = ? + 122.34
