Parallel and Series circuit ISA proof

This was a question on the ISA T23 pre and post instructional survey where the answers are wrong. After doing the math I wanted to cross check it here. Values for pen and paper: R1 : 2K OHMS R2 : 2K OHMS R3 : 5K OHMS R4 : 2K OHMS R5 : 4K OHMS R6 : 7K OHMS R7 : 100K OHMS From top left to bottom R1 & R2 in parallel, R3 in series with Parallel R1&R2. R1, R2, and R3 in parallel with R4 Which is in series with R5. R6 & R7 in series with the above Questions: What is Rtotal? Voltage drop across R1? Voltage drop across R4? Voltage drop across R6? Don't forget the your equivalent resistance calculation!
