A tempo, while travelling at 70 kmph, uses 40% more petrol than it uses while travelling at 50 kmph for travelling a certain distance. Using one litre of petrol, it can travel 19.6 km at 50 kmph. How far can the tempo travel (in KMs) on 10 litres of petrol at a speed of 70 kmph?

OPtion

1) 140
2) 240
3) 248
4) 560
5) 260
6) 270
7) 280
8) 300
9) 180
10) None of these

Solution

At 50 kmph , one km distance uses 1/19.6 litre petrol.
At 70kmph, one km distance uses 1.4/19.6 litre petrol
Distance traveled with 10 ltrs @ 70kmph = 10*19.6/1.4= 140 kms.
