JEE Main 2019 Physics question

Two rods A and B of identical dimensions are at temperature 30°C. If A is heated up to 180°C and B up to T°C, then the new lengths are the same. If the ratio of the coefficients of linear expansion of A and B is 4 : 3, then the value of T is:

• (A)200°C
• (B)270°C
• (C)230°CCorrect
• (D)250°C
