Question

The digit at the ones place of the 2-digit number is 3. The sum of 2-digit number and the number obtained by reversing the digits is 44. Find the 2-digit number.​

Answer 1

Answer:

13

Step-by-step explanation:

Let the digit be ab

Given b=3

Also,ab+ba =44

A two digit number can be written as

ab=(a)(10)+b(1)

So,10a+b+10b+a=44

11a+33=44

(on putting b=3)

11a=11

a=1

Hence the number is ab i.e. 13

Verifying it, 13+31=44
