Let's solve the equation step by step:

Step 1: Calculate the value inside the parentheses - 20-24:3 = 20-8 = 12

Step 2: Calculate the rest of the expression - 90-12:4×6+3×5

Step 3: Perform the division - 12:4 = 3

Step 4: Calculate the multiplication - 3×6 = 18, 3×5 = 15

Step 5: Subtract the division and multiplication - 90-3×6+3×5 = 90-18+15 = 87

Therefore, the answer is 87 (option 4).
