A) 18
B) 52
C) 137
D) 50
Correct Answer: D
Solution :
Let the numbers are 5x and 7x. \[\therefore \] According to question, \[\frac{5x-40}{7x-40}=\frac{17}{27}\] \[\Rightarrow \] \[135x-1080=119x-680\] \[\Rightarrow \] \[16x=400\] \[\Rightarrow \] \[~x=25\] \[\therefore \] The difference between the numbers \[=7x-5x\] \[=2x=2\times 25\] \[=50\]You need to login to perform this action.
