Question

If 6 ÷ 2 # 3 = 9 and 24 ÷ 6 $ 4 = 8, then what will be the value of the given expression?

21 # 3 $ 7

1. 49
2. 9
3. 14
4. 70

Answer 1

Correct Answer - Option 4 : 70

The logic that follows here is

# changes to × and $ changes to +.

6 ÷ 2 × 3 

3 × 3 = 9

and 

24 ÷ 6 + 4

4 + 4 = 8

Now;

21 × 3 + 7

63 + 7 = 70

Hence, "70" is the correct answer.
