Answer» GIVENThe SUM of two numbers is 40 and their difference is 2. TO FINDFind the two numbers. SOLUTION✪ Let the FIRST number be x and second number be y ✞ According to the given condition ✪ Sum of two numbers = 40 → (x + y) = 40 ---(i) ✪ Difference of two numbers = 2 → (x - y) = 2 ----(II) ✞ Add both the equations → (x + y)+(x - y) = 40 + 2 → x + y + x - y = 42 → 2x = 42 → x = 42/2 = 21 ✞ PUTTING the VALUE of x in equation (ii) → x - y = 2 → 21 - y = 2 → y = 21 - 2 = 19 Hence First number = x = 21 Or Second number = y = 19 |
