Please answer fast.

Answer 1

Product of 2 numbers is 2444

product of units digit is 14

14 = 2x7

so one of the number has unit digit as 2 and another number has unit digit as 7

now product of tens digit = 20

20 = 4x5

so we have tens digit one of the number is 4 and another number's tens place digit be 5

we are having 2 possibilities

1) 42 * 57 = 2394 which is not the desired result so it will be discarded

2) 47 * 52 = 2444

so those two numbers are 47 and 52
