Thread: Problem

Got a problem here, if it doesn't make any sense then I probably misread it...

Tara makes X over Y money. James makes X - Y over Y money. Sara makes 2/3 the money Tara makes. If you pool their money together, how much do you have?

If I am not very wrong than

X is the profit Tara earns on investing Y amount of money

(X-Y) is the profit earned by James over the same amount of money

2X/3 is the profit earned by Sara for Y amount of money invested

The total money in the money we have in the end

= (Y + X)+ ((X-Y) +Y) + (2X/3 + Y) = 8X/3 + 2Y

Another possible interpretation is that the "(this) over (that)" statements indicate nothing more than fractions. If so, then:

Tara makes $(x/y). James makes $[(x-y)/y]. Sara makes 2/3 of Tara's amount, or $[(2/3)(x/y)] = $[(2x)/(3y)]. Their total is:

Do you think if they represented Sara's money by 2/3 they will not do so for others


-------------------------------
However the other interpretation can be that X over Y means that X is the amount after the profit has been added to initial amount

Under the alternate interpretation, Sara's money wasn't "two-thirds of a dollar", but "two-thirds of Tara's dollars".

But, as has been demonstrated, other interpretations are possible.
