In a two-digit, if it is known that its unit's digit exceeds its ten's digit by 2 and that the product of the given number and the sum of its digits is equal to 144, then the number is:

A. 24 B. 26
C. 42 D. 46

Read Solution (Total 2)

Let the tens digit be x,
Then, the unit digit is x+2
As per the condition,
(10x+x+2)*(2x+2)=144
(11x+2)^2=144
(11x+2)*(2x+2)=144

Solving, x=2( the tens digit)
Unit digit is 4
Hence the answer is 24(option is A)
