Question

What is the difference between the two digits in a two digit number ?
A. The sum of the two digits is 8.
B. 1/5 of that number is 15 less than 1/2 of 44.
This consists of question and two statements numbered A and B. Decide whether the data provided in the statement(s) aresufficient/necessary to answer the question.

• A. If the data in statement B alone are sufficient to answer the question while the data in statement A alone are not sufficient to answer the question.
• B. If the data in statement A alone are sufficient to answer the question, while the data in statement B alone are not sufficient to answer the question.
• C. If the data either in statements A alone or in statement B alone are sufficient to answer the question.
• D. If the data in both the statements A and B together are not sufficient to answer the question.

Answer 1

The Correct Option is A

The correct option is (A): If the data in statement B alone are sufficient to answer the question while the data in statement A alone are not sufficient to answer the question.
Reason: Statement B provides a clear equation to solve for the two-digit number, allowing us to find the digits and their difference. Statement A only gives the sum of the digits, which is not enough to determine their difference directly.
