Multiple choice

Directions: The following problem consists of a question and two statements which are labelled (1) and (2). Use the data given in statements (1) and (2) together with other available information (such as the numbers in a day, the definition of clockwise, mathematical facts, etc.) to decide whether the statements are sufficient to answer the question. Mark your answer accordingly. In 1990, the ratio of Maruti cars sold to other brand cars sold was 4 to 1. How many other brand cars were sold in 1990? (1) 60,00,000 Maruti cars were sold in 1990. (2) A total of 75,00,000 cars were sold in 1990.

  1. Statement (1) alone is sufficient, but statement (2) alone is not sufficient to answer the question.

  2. Statement (2) alone is sufficient, but statement (1) alone is not sufficient to answer the question.

  3. Both statements (1) and (2) together are sufficient to answer the question, although neither statement alone is sufficient.

  4. Either statement (1) alone or statement (2) alone is sufficient.

  5. Statements (1) and (2) together are not sufficient to answer the question, and additional data relevant to the problem is needed.

Explanation

The ratio of Maruti to other cars is 4:1. Statement (1) gives the number of Maruti cars (4x = 60,00,000), allowing us to find x. Statement (2) gives the total (5x = 75,00,000), also allowing us to find x. Thus, either statement is sufficient.

AI explanation

The ratio of Maruti cars to other brand cars is given as 4 to 1, meaning other cars equal one-fourth of the Maruti cars. Statement 1 gives 60,00,000 Maruti cars, so the other brand cars are 60,00,000 divided by 4, which equals 15,00,000. Statement 2 gives the total cars as 75,00,000, meaning the total 5 parts of the ratio equal this amount, so other brand cars are 75,00,000 divided by 5, which also equals 15,00,000. Therefore, either statement alone is sufficient to find the number of other brand cars sold.
