Question

A two-digit number is such that the product of the digits is 14.When 45 is added to the number, then the digits interchange their places.Find the number.

• A. 72
• B. 27
• C. 37
• D. 14

Answer 1

The Correct Option is B

The Factors of 14 = 1,2,7,14

So, the only two digit numbers possible where reversed change the position are 27 and 72

Now, if we add 45 in the number 27 the added number become 72 which is reverse of 27

27 + 45 = 72

2 × 7 = 14

So, the two digit number is 27

The correct option is (B): 27
