Question

how did 24 and 22 come???
this was the question

The product of two numbers is 528. If the product of their unit’s digits is 8 and the product of their ten’s digits is 4 ; find the numbers.​

Answer 1

because the tens digit is 4 and 4 only has 3 factors which are: 1,2,4

since its has already been established that the unit's digits are 2 and 4,

then that leaves us with only 3 equations with the 10's digit:

12*44=528
14*42$\neq$528
24*22=528

hence, the 2 numbers could have also been 12 and 44, provided, the unit's digits ARE 2 and 4.

hope this helped :)
