Slot – 2 – Quantitative Aptitude – TSD – In a car race, car A beats car B by 45 km


Q. In a car race, car A beats car B by 45 km car B beats car C by 50 km and car A beats car C by 90 km. The distance (in km) over which the race has been conducted is?
  1. 475
  2. 450
  3. 500
  4. 550
Answer: 2

Solution:
The distance between car B and C when car A reaches the destination = 90 – 50 = 40 km
Now when car B will travel next 50 km , it will reach the destination point and the distance between car B and C will be 45km.
Thus we can say for each 50 km that Car B travels , distance b/w B and C increases by 5 km
Thus the required distance = 50 *45/5 = 450 km
