Read the following table carefully and answer the questions given below. The table shows the total number of bikes sold by two (X and Y) different companies in four (K, L, M, and N) different cities and the total number of cars sold by these two companies in these cities. The table also shows the total number of bikes sold by company Y in these cities.
The total number of bikes sold by X in city M is what percentage more or less than the total number of cars sold by X and Y together in city N?
- A.
2%
- B.
0%
- C.
5%
- D.
10%
- E.
7.5%

Show answer & explanation
Correct answer: B
Concept
A percentage change of one quantity relative to another is found with the formula: percentage change = ((value − reference) / reference) × 100, taking the reference (the "than" quantity) as the base. When the two quantities being compared are equal, the numerator is zero, so the percentage change is exactly zero — neither more nor less.
Application
Read the two required quantities from the table:
Bikes sold by X in city M: the table gives bikes by (X and Y) in M = 440 and bikes by Y in M = 90, so bikes by X in M = 440 − 90 = 350.
Cars sold by X and Y together in city N: the table states this directly as 350.
Apply the formula with the cars figure as the base: ((350 − 350) / 350) × 100 = (0 / 350) × 100 = 0.
Cross-check
The two figures, 350 and 350, are identical, so there is no difference in either direction. A non-zero result would require the two quantities to differ, which they do not. Hence the bikes sold by X in M differ from the cars sold by X and Y in N by 0.
