Answer: (4) 20
Explanation:-
Let be the Y = P
X is 50 % larger than Y ,
Then, X = 150 P/100 = 15 P/10
Z is 25 % larger than Y,
Then, Z = 125 P/100 = 5 P/4
X is larger than Z = 15 P/10 – 5 P/4
= (30 P – 25 P)/20
= 5 P/20
= P/4
In percent X larger than Z = (P/4) x 100/(5 P/4)
= P x 4 x 100/4 x 5 P = 20 %
Hence, the answer is (4) 20 %.
