A train travels at an average speed of 100 km per hour without stoppage and with stoppages it covers the same distance at an average speed of 80 km/hr. How many minutes per hour does the train stop?
Due to stoppage, it covers 20 km less. Time taken to cover 20 km = 20/100 × 60 = 12 min.
31.98% of 224.99 = 24.98% of ? + 9.91% of 499.99
420.11 ÷ 13.98 × 5.14 – 124.9 = √?
41.97 × 5.12 ÷ 2.99 + 49.89 = ?× 1.99
630.11 ÷ 20.98 × 5.14 – 125.9 = √?
