In a race of 1 km, A can beat B by 40 m and B can beat C by 50 m. With how much distance can A beat C in a 0.5 km race? |
A) 42 m
B) 43 m
C) 44 m
D) 46 m
Correct Answer: C
Solution :
When A runs 1000m, |
then B runs 960 m, |
and when B runs 1000 m, |
then C runs 950 m. |
i.e. C runs 5% less than B |
So, when A = 1000 |
\[\Rightarrow \] B = 960 |
\[\Rightarrow \] C = 912 |
\[\therefore \]When A = 500 \[\Rightarrow \] C = 456 |
So, A will beat C by 44 m. |
