1.53 + 4.73 + 3.83 - 3 x 1.5 x 4.7 x 3.81.52 + 4.72 + 3.82 - 1.5 x 4.7 - 4.7 x 3.8 - 1.5 x 3.8
Apply a3 + b3 + c3 - 3abca2 + b2 + c2 - ab - bc - ca = a + b + c
Hence the answer is 1.5 + 4.7 + 3.8 = 10.

92613 x 62742241 = ? + 89
Find the value of '?'
Given 92613 x 62742241 = ? + 89
Using unit digit method,
On LHS,

? + 89
=> ? = ...1 - 89 = last digit is 11- 9 = 2
or
=> ? = ...9 - 89 = last digit is 9 - 9 = 0
Here in the options last digit 2 is option C.
