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.
72 + 37 = 6328; 54 + 13 = 4504; 61 + 53 = ?
Option 1: 4524
Option 2: 5244
Option 3: 5424
Option 4: 5214
Correct Answer: 5244
Solution :
Given:
72 + 37 = 6328
54 + 13 = 4504
Here, the pattern followed is –
72 + 37 = 6328→72 – 9 = 63; 37 – 9 = 28→6328
54 + 13 = 4504→54 – 9 = 45; 13 – 9 = 04→4504
Similarly, 61 + 53 = ?→61 – 9 = 52; 53 – 9 = 44→5244
So, 5244 is the required answer. Hence, the second option is correct.
