8 & 6 are both even numbers
The multiplier & the digit in the hundredth’s place must both be ODDxODD or EVENxEVEN
1,23,632 is a multiple of eight
12,12,1 (16) =(4 x 4)
4 is even, 1 is odd
12,12,116 is not a multiple of 8
Parmar was recently given the ‘Innovative Teacher’ award by the Indian Institute of Management, Ahmedabad for his new findings
A simpler method for problem solving!
