Question

A two - digit number is such that the product of its digits is 35. If 18 is added to the number, the digits interchange their places write down their linear equations

Answer 1

1st digit = x
2nd digit = y
Product of two digits = 35

Let x = 5 & y = 7
5×7= 35

Of we add 18 to 57 then the answer is 75 so they interchange their positions.

The two digits no. is 57. Ans.
