John earns 33.33% more than Peter. By what percentage is Peter’s earning less than that of John’s?**(A)** 22 %

**(B)** 25 %

**(C)** 26 %

**(D)** 23 %

**Answer:** **(B)****Explanation:** Let John’s income be j and Peter’s income be p. Then,

j = p + p × 33.33% = p + p × 100⁄3 % = p + p × 1/3 = 4p/3

⇒ p = 3j/4 = (4 – 1)j/4 = j – j/4 = j – j × 1/4 = j – j × 100⁄4 % = j – j × 25%.

Therefore, Peter’s earning is less than John’s earning by 25%.
