On a certain day, the exchange rate was 60 U.S. dollars for 50 euro. How many U.S. dollars were 60 euro worth that day?

Fudgin [204]

The exchange rate can be expressed as: 60 dollars / 50 euro

So 60 euros * 60 dollars / 50 euro = 60 * 60 / 50 dollars (the euros cancel out)
= 3600 / 50 dollars
= 360 / 5 dollars
= 72 dollars

THE RATIO OF ANNUAL INCOMES OF A AND B IS 4 :3 AND THEIR ANNUAL EXPENDITURE IS 3 :2 IF EACH OF THEM SAVES SHILLINGS 1000 A YEAR

pickupchik [31]

Answer:

Annual Income of A= $4x=4*1000=4000$

and

Annual Income of B= $3y=3*1000=3000$

Step-by-step explanation:

Given Data:

Ratio of annual income of A and B=4:3

Ratio of expenditures of A and B=3:2

Saving of A and B=1000

Required: Annual Income of A and B=?

Solution:

If ratio of income of A and B is 4:3

then let Income of A= $4x$ and Income of B= $3x$

If ratio of expenditure of A and B is 3:2

then let expenditure of A= $3x$ and expenditure of B= $2x$

Therefore,

$4x-3x=1000$ ........... $Eq(1)$

and $3x-2x=1000$ .......... $Eq(2)$

subtracting Eq(1) and Eq(2), we get

$4x-3y=1000\\-(3x-2y)=1000\\......................\\x-y=0$

$x=y.....Eq(3)$

putting $x=y$ in Eq(1), we get value of $x$ as

$4x-3x=1000$

$x=1000\\thus, y=1000 \\$ because x and y are equal in Eq (3)

Now, Annual Income of A= $4x=4*1000=4000$

and Annual Income of B= $3y=3*1000=3000$
