1.

Note: 3.84% = 1/26 of fraction.The Average Speed of train in September to February is 195 km/h and March to August is 260 km/h. Then find the ratio of the cost of travel in March to August cycle to September to February Cycle of travelling in train.1). 3 : 82). 1 : 23). 3 : 44). 1 : 7

Answer»

DISTANCE travelled by TRAIN = 2600[1 - (1/26) - (1/52)] = 2450 Km

Time TAKEN in MARCH to August cycle = 2450/260

Cost in March to August cycle = 2450 × 130/260

Time taken in September to February cycle = 2450/195

Cost in September to February cycle = 2450 × 78/195

∴ Required Ratio = 5 : 4
