The sum of 3 single digit numbers is 15 less than their product. If we subtract 2 from first given number, then sum of these numbers will become 7 more than their product. The product of given 3 numbers will be?
6
8
12
24
Explanation:
Let the three digits of the number be x, y and z.
Then, x + y + z = a and xyz = b
A/C, a + 15 = b ----(i)
and, a - 9 = b + 2yz ----(ii)
From eq(i) and eq(ii), we get
=> 2yz = 24.
Thus, yz = 12.
Possible answers are 24, 48,120.
Hence, by hit and trial, answer is 24.
