Answer:
\boxed{5}
5
Step-by-step explanation:
Given:
x : y = 3 : 2
\bf{By\: componendo\: and\: dividendo:}Bycomponendoanddividendo:
if a : b then ( a + b ) : (a - b)
So:
x : y = 3 : 2
==> ( x + y) / (x - y) = (3 + 2 )/( 3 -2)
==> ( x + y ) / ( x - y ) = 5 / 1
==> 5
\bf{Another\: method}Anothermethod
x : y = 3 : 2
Let x be 3 k
y is 2 k
So:
(x + y) / (x - y)
==> ( 3 k + 2 k ) / ( 3 k - 2 k )
==> 5 k / k
==> 5
