The following questions have three statements. Study the question and the statements and decide which of the statement(s) is/are necessary to answer the question. Sum of two positive integer numbers A and B is 97. Find the product of A and B. Statement I∶ A, B < 50 Statement II∶ A = B + 1 Statement III∶ The tens digit of both the numbers is same. Correct Answer Any statement alone is sufficient to answer the question.

Given that∶

A + B = 97

Statement I∶ 

A, B < 50 and A + B = 97

Hence, only possible values of A and B are 49 and 48.

∴ We can get the product of A and B.

Statement II∶

A = B + 1 and A + B = 97

Solving them, we can get A = 49 and B = 48

∴ We can get the product of A and B.

Statement III∶ 

The tens digit of both the numbers is same and

A + B = 97

Hence, only possible values of A and B are 49 and 48.

∴ We can get the product of A and B.

∴ Any statement alone is sufficient to answer the question.
