Question

A billiard ball is hit from a point on the vertical board of the table close to the pocket D as shown in the figure. It meets the horizontal board at an angle of 45⁰, and continues following the arrow. Into which pocket will the ball fall?

Solution

The correct option is D
None of these

1.The billiard bal starts from 3 cells away from D. On side AD, hits at 3 cell away from
D on CD, hits side BC 3 cells away from C and hits AB at a point 1 cell away from A.
From this point it will hit 1 cell away from A on side AD then 1 cell away from C on side BC one cell away from C on side CD and it comes to 3 cells away from A on side AD. From this point (follow the arrows shown ) it will move as before and in a few steps to the starting point and it will trace the same path without reaching any pocket.
