Step-by-step explanation:
The no.=xy
When we add x and y we should get 6.
Let's check which numbers are possible
60, 51, 42, 33, 24, 15, 06
But the no. should interchange when we subtract it by 18 so let's check which numbers are appropriate.
The only number which interchanges is 42.
Therefore 42 is the answer.
