Which choice provides the answer in the following: 7 + 2 = 59, 5 + 3 = 28, 9 + 1 = 810, 2 + 1 = 13 then 5 + 4 = _____?
- 19
- 133
- 259
- None of these
Explanation
The pattern for each equation is as follows:- Subtract the second number from the first number.
- Add the first and second numbers.
- Combine the two results to form a new number.
Let's apply this logic to the given examples:
7 + 2 = 59
7 - 2 = 5
7 + 2 = 9
Combined: 5 followed by 9, which is 59.
5 + 3 = 28
5 - 3 = 2
5 + 3 = 8
Combined: 2 followed by 8, which is 28.
9 + 1 = 810
9 - 1 = 8
9 + 1 = 10
Combined: 8 followed by 10, which is 810.
2 + 1 = 13
2 - 1 = 1
2 + 1 = 3
Combined: 1 followed by 3, which is 13.
Solving for 5 + 4
Applying the same logic to 5 + 4:
5 - 4 = 1
5 + 4 = 9
Combined: 1 followed by 9, which is 19.
