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 |
