finding an unknow value of resistance (HELP REQUIRED!!!)

1. Homework Statement

Two resistors in parallel, R1 of 470 ohms and R2 of unknow value, are connected in series with two more parallel resistors R3 of value 1kohm and R4 of value 270 ohms. The supply is 110 V dc and the potential difference across the parallel pair of resistors R3 and R4 is 60V.

Ive been looking at this question for a while and a bit of help would be greatly appreciated.

Determine the value of resistance R2


2. Homework Equations

V1 = (R1/R1+R2) Vin

Transposed to find R2. Ive came out at an answer of 564 ohms. Anyone able to check im correct and help me on this problem? Thanks in advance
