Question:

The product of 2 numbers is 1575 and their quotient is $frac{9}{7}$. Then the sum of the numbers is

a. 74

b. 78

c. 80

d. 90

Answer:

Let the numbers be x and y.

$therefore xy=1575$ and $frac{x}{y}=frac{9}{7}$

$therefore frac{xy}{(frac{x}{y})}=frac{1575}{(frac{9}{7})}$

$therefore y^2=1225$

$therefore y=35$

Hence, $x=45$

So, sum of the numbers

$=x+y$

$=35+45$

$=80$
