Question

Which of the following number will come in the box when we do multiplication of $82\times 94$ by base method?

• A. 50
• B. 86
• C. 78
• D. 176

Answer 1

The correct option is B 86


Since deviation is -8 for 82, which means base is taken as 90.
Therefore, $86\times 90$ + (-32)
= 7740 – 32 = 7708
