The total amount is $ 780
<em><u>Solution:</u></em>
Let the total amount be "x"
Given that,
First person gets $ 268
Second person gets $ 200
Third person gets 40 %
This means, third person gets 40 % of total amount
Third person = 40 % of x

We know that, total amount is equal to sum of amount got by all three persons
Total amount = first person + second person + third perosn

Thus the total amount is $ 780
