Question

Some equation are solved on the basis of the basis of a certain system.

8 × 2 × 9 = 73

6 × 4 × 5 = 59

What is the result of the equation given below in the same system ?

4 × 9 × 7 = ?

1. 252
2. 29
3. 20
4. 42

Answer 1

Correct Answer - Option 4 : 42

The logic follows here is:

82 - 9 = 73

64 - 5 = 59

Similarly;

49 - 7 = 42

Hence, "42" is the correct answer.
