If ‘L’ = +, ‘M’ = -, ‘N’ = ×, and ‘O’ = ÷, which equation is incorrect?

1. 10 L 5 N 2 M 5 = 15
2. 18 O 3 L 4 N 2 = 14
3. 20 M 4 O 2 N 3 = 24
4. 16 N 2 O 4 L 2 = 10

Correct answer: 20 M 4 O 2 N 3 = 24

Solution

Substitute the symbols: M = -, O = ÷, N = ×. Then evaluate the expression using BODMAS/PEMDAS. The given equation does not satisfy the equality after correct calculation, so it is the incorrect one.
