Problem

Two rods A and B of identical dimensions are at temperature

30^\circ\text{C}

. If A is heated upto

180^\circ\text{C}

and B upto

T^\circ\text{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.

230^\circ\text{C}

270^\circ\text{C}

200^\circ\text{C}

250^\circ\text{C}
