Q.Find the last 2 digits of: 65*29*37*63*63*71*87*85

The last two digits are 25

firstly remove the two 5's from 65 and 85 which gives you 5*5=25

Now find out the unit's digit from the multiplication of rest of the numbers which comes out to be 9.

Now 25 multiplied by 9 will always give 25 at the lat two digits..

for ex 25*9=225

25*19=525

25*29=725
