Find two 2-digit numbers such that their product is 850, the product of their unit’s digit
is 20 and the product of their ten’s digit is 6.
Answers
the product of their units digit is 32...
The only two digits that have product 32 are 4 and 8 So their units digits are 4 and 8
...and that of tens digit is 18...
So their tens digits could be 3 and 6 or 2 and 9 The possibilities are: 34 and 68 64 and 38 24 and 98 94 and 28
The product of two 2-digit numbers is 2632...
So we multiply them to find out: 34×68 = 2312 64×38 = 2432 24×98 = 2352 94×28 = 2632 So they are 94 and 28.
