Thanks for accepting my request. I am horrible at Maths. I often take photos of my P3 girl's school Maths questions and post them in my Facebook wall for help. Now I can post here in this group for the Maths experts to help me out ☺

I have solved the problem using algebra method. G= 80 but can anyone shows me how to do e ratio our other method as I have difficulty explaining to my girl who doesn't understand algebra yet. Many thanks
