In a 1500-m race, if A beats B by 100 m and B beats C by 150 m, then by what distance (in m) does A beat C?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 240.
The ratio of the distance b/w A and B = 1500 : 1400 = (15 : 14) × 100
The ratio of the distance b/w B and C = 1500 : 1350 = (10 : 9) × 140
So, the ratio of A : B : C = 1500 : 1400 : 1260
So, the difference between A and C = 1500 - 1260 = 240
A beat C by 240 m.
