A) 3 : 7
B) 10 : 3
C) 3 : 10
D) None of these
Correct Answer: C
Solution :
We have, \[a=12,\,\,b=15,\,\,c=25\] and \[x=312\] \[\therefore \] \[A=\frac{ax}{a+b+c}=\frac{12\times 312}{12+15+25}=72\] \[B=\frac{bx}{a+b+c}=\frac{15\times 312}{12+15+25}=90\] and \[C=\frac{cx}{a+b+c}=\frac{25\times 312}{12+15+25}=150\] \[\therefore \] \[B-A=18\] and \[C-B=60\] Thus, their ratio = 18 : 60 = 3 :10You need to login to perform this action.
