Answer:
Stephen's wife got £354 more than his son.
Step-by-step explanation:
Given:
Amount of Lottery = £2950
Now Given:
Stephen & Richard share a lottery amount in the ratio 2 : 3
Let the common factor between them be 'x'.
So we can say that;
Dividing both side by 5 we get;
So we can say that;
Stephen share would be =
Now Given:
Stephen then shares his part between himself, his wife & their son in the ratio 3 : 5 : 2.
Let the common factor between them be 'y'.
So we can say that;
Dividing both side by 10 we get;
So Stephen's wife share =
And Stephen's son share =
Now we need to find how much more her wife got then her son.
