Solution

The correct option is D A is wrong and B is correct
Initial and final velocities don't change because of the shock absorbers, they just increase the time of action of impulsive force and thus the ratio change in momentum to time taken is reduced, thus force acting is also reduced.

Q. An automobile plant contracted to buy shock absorbers from two suppliers X and Y. X supplies 60% and Y supplies 40% of the shock absorbers. All shock absorbers are subjected to a quality test. The ones that pass the quality test are considered reliable. Of X's shock absorbers, 96% are reliable. Of Y's shock absorbers, 72% are reliable.

The probability that a randomly chosen shock absorber, which is found to be reliable, is made by Y is
