IMO (B).

The area of the triangle remains same so 1/2 * 3 * 4 = 1/2 * 5 * x
where x = PR

Hence PR = 12/5

12/5

make sure you know the greek guy's formula. pythagoras?
then you know that QS is 5 (3-4-5)
and then you can see the jackpot.

3 times 4 times 1/2 = 5 times PR times 1/2

therefore PR is 12/5
