Show answer
Correct Option: B
Explanation:
To multiply any number by 11 do the following:
Working from right to left
Write the rightmost digit of the starting number down.
Add each pair of digits and write the results down, (carrying digits where necessary right to left).
Finally write down the left most digit (adding any final carry if necessary).
For 8 6
8 (8+6) 6
8 (14) 6
(8+1) 4 6
86×11= 946
So option B is the correct answer.
