Kirchoffs Law Parallel Circuit-with only I and R given.Solvable?

Hi all
I`m doing my first ever Physics course, and i`ve hit a brick wall with Kirchoffs Law.
I understand what the laws are i just can`t seem to get the right answers on a particular question.
I then decided to cheat(because i exhausted all my options in trying to solve it) which i really don`t like doing.My tutor then said I also need to show my workings out,and so this is where i`m stuck i`ve tried everything i could find to do with Kirchoffs Laws but still no luck.

I`ve filled in the template the best i could, but if anymore information is needed please state.

Thanks a ton to anyone who can and is willing to help.

1. The problem statement, all variables and given/known data
The particular Question is number 4 on Teaching Advanced Physics 117- 5: Questions on Kirchhoff’s laws.(http://ift.tt/1kAHx3K)
There are 6 total resistors, 1 on first reciprocal,3 on the second and 2 on the bottom.
The question is "Ammeter A5 reads 3 A. All the resistors have the same value of 10 Ω. What are the readings on ammeters A1 to A8 and what is the terminal voltage of the battery?"

2. Relevant equations

Tried Ohms Law and Kirchoffs laws.

3. The attempt at a solution

I tried using Ohms law i.e V=IR, I=V/R etc i`ve also used some equations i saw that was saying about to find the total resistance use 1/R1+1/R2 etc also tried using Kirchoffs Law.
