Question

Identify the missing numbers on the right side so that both sides are equal.
$23+8=\underset{–}{}\underset{–}{}-\underset{–}{}\underset{–}{}$

• A. 31 and 1
• B. 35 and 4
• C. 39 and 7
• D. 40 and 1

Answer 1

The correct option is B 35 and 4

Left side:
$23+8=31$
Right side:
Option A: $40-1=39$
Option B: $39-7=32$
Option C: $35-4=31$
Option D: $31-1=30$

Option C is equal to 31, i.e., equal to the total of the left side.

So, Option C is the correct answer.
