Question

When 99 is divided by 7, the remainder obtained is equal to

• A. 2
• B. 3
• C. 1

Answer 1

The correct option is C 1

Let's use repeated subtraction for dividing 99 by 7.

99 - 7 = 92
92 - 7 = 85
85 - 7 = 78
78 - 7 = 71
71 - 7 = 64
64 - 7 = 57
57 - 7 = 50
50 - 7 = 43
43 - 7 = 36
36 - 7 = 29
29 - 7 = 22
22 - 7 = 15
15 - 7 = 8
8 - 7 = 1

So, 7 cannot be further subtracted from 1.
Thus, the remainder is 1
