A two-digit number is such that the product of the digits is 8. When 18 is added to the number, then the digits are reversed. The number is:
ANSWER :- b
Solution :- Let the two numbers be x and y respectively.
According to the question :
xy = 8 _______(i)
10x + y + 18 = 10y + x
=> 10x - x + 18 = 10y - y
=> 9(x + 2) = 9y
=> x + 2 = y ______(ii)
Putting the value y in equation (i) we get,
x(x + 2) = 8
=> x² + 2x - 8 = 0
=> x² + 4x - 2x - 8 = 0
=> x(x + 4) - 2(x + 4) = 0
=> (x - 2) (x + 4) = 0
=> x = 2 or - 4
Putting the positive value of x in equation (ii),
2 + 2 = y = 4
Hence, The number is : 2 × 10 + 4 = 20 + 4 = 24
