Answer 1

Answer:

this is first answer

Factor 1938.

Step-by-step explanation:

1938 = 2 x 969 = 2 x 3 x 323 = 2 x 3 x 17 x 19.

The two desired numbers are products of these factors.

Since the product of the unit's digits is 28, a little trial inspection leads to

(3x19) and (2x17), i,e, 57 and 34,

which satisfy the ten's digit rule as well.

So the numbers are 34 and 57
