Question

A can beat B by 20m in 200m race,B can beat c by 10m in 250m race,by how many meters can A beat C in a 100m race?

Answer 1

Answer:

A kaleidoscope works by reflecting light that bumps into a reflective surface such as a mirror. It has two or more mirrors placed at an angle to each other. The mirror assembly is surrounded by a case, with an eye hole at one end of the mirrors and a collection of objects at the other end.

Answer 2

Answer:

When A completes 200 m B completes 180 m and C completes 162 m.

Now, when B completes 180 m, C completes 162 m.

So, when B completes 300 m, C will complete 300*162/180 = 1620/6 = 270 m.

Therefore, B beats C by 30 m.
