The correct option is
B 2010=3×54+1×53+2×51We know that, 51=5,52=25,53=125,54=625,55=3125
Since, 3125>2010. So, we take upto 54
Now, if we divide 2010 by 625 we get quotient as 3 and remainder as 135.
∴2010=3×54+135
Now, 135>125=53
If we divide 135 by 125 we get quotient as 1 and remainder as 10
∴2010=3×54+1×53+10
Since, 10<52 and 10>51
So, divide 10 by 5 we get quotient =2 and remainder =2.
Thus, 2010=3×54+1×53+2×51
