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 ratio of the total number of cars sold by X to Y in city L is 3:4 respectively. Find the total number of cars sold by X in city L is how many more or less than the total number of bikes sold by Y in N.
- A.
225
- B.
210
- C.
195
- D.
145
- E.
125
Show answer & explanation
Correct answer: A
Concept
In a table-based Data Interpretation question, a combined total can be split into its parts using the given ratio. If a quantity is divided in the ratio a : b, then the first share equals total × a/(a+b) and the second share equals total × b/(a+b). To compare two quantities, compute each independently from the table and then take their difference; a positive difference means more and a negative difference means less.
Application
From the table, the total cars sold by both companies (X and Y together) in city L is 980.
The cars in city L are split between X and Y in the ratio 3 : 4, so the total number of parts is 3 + 4 = 7.
Cars sold by X in city L = 980 × 3/7 = 140 × 3 = 420.
From the table, bikes sold by company Y in city N = 195.
Required difference = 420 − 195 = 225. Since 420 is greater than 195, X’s cars in L are 225 more than Y’s bikes in N.
Cross-check
Verify the split: cars by Y in L = 980 × 4/7 = 560, and 420 + 560 = 980, which matches the table total for L. Adding the difference back also checks out: 195 + 225 = 420, the cars sold by X in L. Hence the result 225 is consistent.
