Question

KnowledgeBoat · Accepted Answer

Given, ⇒ ⇒ a + b = 8 .........(1) ⇒ b - a = 2 .........(2) Adding equations (1) and (2), we get : ⇒ (a + b) + (b - a) = 8 + 2 ⇒ 2b = 10 ⇒ b = ⇒ b = 5. Substituting value of b in equation (1), we get : ⇒ a + 5 = 8 ⇒ a = 8 - 5 = 3. Hence, Option 4 is the correct option.
