Default VM2- Square of no. having 5 in the end....
One method i explain with my post ..multiplication of two digit number...
Another method...

take square of digits having 5 in end...

35^2=1225
75^2=5625
195^2=38025

Got any clue...
here clue is multiply 5 to 5 ...write 25,
than multiply the no in front of 5 with its next no.
say 3 *4=12 so square of 35 is 1225
7*8= 56 square of 75 is 5625
19*20=380 so square of 195 is 38025

Enjoy.... Square...
