A) 5
B) 35
C) 60
D) - 45
Correct Answer: D
Solution :
(d): (i) Since, a, b, c are in ascending order, b is the median. (ii) \[AM=\frac{a+b+c}{3}=130\Rightarrow a+c+120=390\] \[\Rightarrow c+a=270\] Also, \[c-a=60\] \[\Rightarrow c=165\] \[\Rightarrow b-c=120-165=-\,45\]You need to login to perform this action.
