If x, y, z are three positive integers such that x is greater then y and y is greater than z, then which of the following is definitely true ?
A. x% of y is greater than y% of z
B. y% of x is greater than z% of y
C. z% of x is greater than y% of z
D. All of these
Answer: Option D
Solution(By Examveda Team)
(a) x% of y = $$\frac{xy}{100}$$ and y of z = $$\frac{yz}{100}$$x > y, y < z
⇒ xy > yz
⇒ $$\frac{xy}{100}$$ > $$\frac{yz}{100}$$
⇒ x% of y > y% of z
(b) y% of x = $$\frac{xy}{100}$$ and z% of y = $$\frac{yz}{100}$$
As proved above, y% of x > z% of y
(c) z% of x = $$\frac{xy}{100}$$ and y% of z = $$\frac{yz}{100}$$
x > y
⇒ xz > yz
⇒ $$\frac{xz}{100}$$ > $$\frac{yz}{100}$$
⇒ z% of x > y% of z
