Question : Directions: Some equations are solved based on a certain system. Find the correct answer for the unsolved equation on that basis.
678 = 366; 567 = 255; 946 = ?
Option 1: 334
Option 2: 499
Option 3: 699
Option 4: 634
Correct Answer: 634
Solution :
Given:
678 = 366, 567 = 255, 946 = ?
The numbers on the L.H.S. and R.H.S. of the equation have a difference of 312 in common.
Like, 678 = 366→678 – 312 = 366
And, 567 = 255→567 – 312 = 255
Similarly, follow the same pattern for 946 = ?→946 – 312 = 634
So, 634 is the correct answer. Hence, the fourth option is correct.
