Ratio of two sums of money is 4:3

if larger sum of money is increased by $40, the ratio becomes 2:1.

What are sums of money ?

How to solve this ?

Solution

(4/7)*x+(3/7)*y=4:3

cant understand it....

solving this i get x=160 and y=120

is it correct ? - June 17th 2011, 01:10 AMSudharakaRe: Ratio

so those

**are**in ratio 4:3.

But adding $40 to $160 give $200.

, or 5:3, not 2:1. - June 17th 2011, 03:11 AMDevenoRe: Ratio
it may be easier to solve the two equations writing them like this:

3x = 4y

x+40 = 2y

one way of doing this, is to write (from the 2nd equation):

x = 2y - 40.

now use this in the first equation. - June 17th 2011, 04:53 AMhaftakhanRe: Ratio
i was about to post the correct answer but the light went off.

x=80 and y=60 - June 17th 2011, 03:08 PMmr fantasticRe: Ratio

ratio of two sums = 4 : 3 = ........... (1)

When $40 is increased to the larger sum, the ratio is = .........(given)

=

=

=

=

By replacing the value of x in the first equation, we get $80 and $60.

So the sum of $80 and $60 = $140.

We had $140. Answer.

I think you have understood this. All the best
