Hi,

Just realised that I posted at the wrong level...no wonder nobody answers.....

I am stumbled by this Maths question below:-

Simeon and Alvin had 116 marbles at first.
After Simeon bought another 8 marbles and Alvin gave away 20 of his marbles to his sister,
they both had the same number of marbles left. How many marbles did Alvin have at first?

I hope someone can explain how to get the answer.

Thank you for your help

Solution:

Total now -- 116+8-20= 104
Each now -- 104/2= 52
Alvin at first -- 52+20 =72

Ans: 72 marbles
