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?
Answer & explanation
Correct answer: option 4
It is given that A beats B by 100 m
i.e. Distance travelled by A is 1500 m and B is 1400 m respectively
So , A : B = 1500 : 1400
Similarly, the Distance travelled by B and C when B beats C is 1500 m and 1350 m respectively
B : C = 1500 : 1350
To find relation b/w A & C
\(\frac{A}{C}\) = \(\frac{A}{B}\) × \(\frac{B}{C}\)
\(\frac{A}{C}\) = \(\frac{1500}{1400}\) × \(\frac{1500}{1350}\)
= \(\frac{15}{14}\) × \(\frac{10}{9}\)
A : C = 150 : 126
So , If A travels 1500 meter then C will travel 1260 meter .
So , Distance by which A beats C = 1500 - 1260 = 240 meter
