In a two-digit number, 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
Detailed Solution for RRB Group D Mock Test - 8 - Question 60
Let the ten's digit be x
Then, unit's digit = x + 2
Number = 10x + (x + 2) = 11x + 2
Sum of digits = x + (x + 2) = 2x + 2
∴ (11x + 2)(2x + 2) = 144
⇒ 22x2 + 26x - 140 = 0
⇒ 11x2 + 13x - 70 = 0
⇒ (x - 2)(11x + 35) = 0
⇒ x = 2
Hence, required number = 11x + 2 = 24.
