Another physics question, please answer this?

An 84-ohm resistor has a current of 0.62 A and is connected in series with a 130-ohm resistor. What is the emf of the battery to which the resistors are connected?

The answer is 130 V, but what is the solution? Coz I always get something like 133.6.

well V = IR.. good were on the same page. The resistance of the circuit is 130 + 84 = 214 and the current is a constant 0.62 V = .62 * 214 = 132.68. 130 is just rounded I'm sure.
