Question : Directions: In the following question, some equations are solved based on a certain system. Find out the correct answer for the unsolved equation on that basis.
1 × 2 × 4 = 212, 5 × 6 × 8 = 654, 3 × 7 × 2 = ?
Option 1: 173
Option 2: 713
Option 3: 731
Option 4: 317
Correct Answer: 731
Solution :
Given:
1 × 2 × 4 = 212, 5 × 6 × 8 = 654, 3 × 7 × 2 = ?
Interchange the position of the first two numbers and half the third number, to obtain the resultant.
Like, 1 × 2 × 4 = 212→1 × 2 × (4 ÷ 2) = 212
And, 5 × 6 × 8 = 654→5 × 6 × (8 ÷ 2) = 654
Similarly, follow the same pattern for 3 × 7 × (2 ÷ 2) = ?→731
So, 731 is the answer to the given equation. Hence, the third option is correct.
