Explanation Current Ages: Let Zoya’s current age be x Then, Zaid’s current age is 6 x (since he is six times as old as Zoya). The sum of Ages in 7 Years: In 7 years, Zoya's age will be x + 7 x + 7 and Zaid's age will be 6x + 7 6 x + 7 . The sum of their ages in 7 years will be ( x + 7 ) + ( 6 x + 7 ) = 49 . Step 1: Formulate the Equation x + 7 + 6 x + 7 = 49 7 x + 14 = 49 Step 2: Solve for x Subtract 14 from both sides: 7 x = 35 Now divide by 7: x = 5 So, Zoya’s current age is 5 5 years and Zaid’s current age is: 6 x = 6 × 5 = 30 Step 3: Determine Zaid’s Age When Zoya Was Bor n When Zoya was born, Zaid would have been: 30 − 5 = 25
