In a 150-m race, if R gets a 5-metre head start, then he would beat S by 35 metres. If S gets a 25-metre head start in a 100-metre race, then _______ would win the race by ________ metres.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. S; 5.44.
Condition 1:
R : S
Distance 145 : 115
= 29 : 23
Condition 2:
R : S
Distance 100 : 75
23 → 75
1 → 75/23
R → 29 → 94.56 (Distance travelled by R in 100 m race)
So, S win the race = 100 - 94.56 = 5.44 m
