Two numbers are in the ratio of 3:4. If 9 is subtracted from their sum, the result is 40. What is the greater number?

F. 35
G.21
H.28
J.49

Respuesta :

Answer:

H.28

Step-by-step explanation:

x : y = 3 : 4

=> 4x=3y   => x=3y/4 -----(1)

(x+y)-9=40

=>x+y=49

using (1)

3y/4 +y= 49

y=28

substituting y in (1)

x=21

hence 28 is greater.
