Let the fare of one ticket from city A to city B = ₹ x And the fare of one ticket from city A to city C = ₹ y According to the question : 3x + 2y =173 ....(1) 2x + 3y =177 ....(2) When equation (1) is multiplied by 3 and equation (2) is multiplied by 2 Then, 9x + 6y =519 ....(3) 4x + 6y =354 ....(4) Subtracting equation (4) from equation (3), we get 5x = 165 ⇒x=₹33 Hence, the fare for city B from city A will ₹ 33.
