error analysis???

Question

Q.In arihant objective i calculate the following problem and found out the correcr answer to be (d),but in key it is (b),please clarify.

If the error in the measurement of the momentum of a particle is (+100%).Then, the error in the measurment of the kinetic energy is

(a)400% (b)300%

(c)100% (d)200%

T'S GIVEN THAT THE PERCENTAGE ERROR IN MOMENTUM MEASUREMENT AS 100%, the question is the percentage error in kinetic energy, answer: if % error is more than 5-6% ,the error analysis can't be applied and we have to apply conventional method. so ur answer is right as it is not 200% but 300% will be the increase in k.e.
