Question
n a 100 m race, A beats B by 10 m and C by 13 m. In a race of 180 m, B will beat C by:
Solution
In a 100m race, A beats B by 10m. This means B runs 90m when A runs 100m.
Similarly, A beats C by 13m. This means C runs 87m when A runs 100m.
So, when B runs 90m, C runs 87m.
Now, we need to find out how much B will beat C in a 180m race.
First, we find out how much distance C covers when B runs 180m.
If B's 90m = C's 87m, Then, B's 180m = C's (87/90)*180 = 174m.
So, in a 180m race, B will beat C by (180-174) = 6m.
