by

A. 40, 86
B. 50, 17
C. 44, 22
D. 65, 20

🧠 Explanation (Math):

Given: Sum of two numbers is 66; one number equals their difference
Step 1: Let larger = a, smaller = b, with a + b = 66 and b = a − b
Step 2: From b = a − b ⇒ 2b = a ⇒ a = 2b
Step 3: Substitute in a + b = 66 ⇒ 2b + b = 66 ⇒ 3b = 66 ⇒ b = 22
Step 4: Then a = 2b = 44
Final Answer: 44, 22
