A) 125
B) 120
C) 105
D) 90
Correct Answer: C
Solution :
Given, \[4A=5B=7C\] \[\Rightarrow \] \[\frac{A}{35}=\frac{B}{28}=\frac{C}{20}\] So, \[A & :\,B:\,C=35\,\,:\,\,28\,\,:\,\,20\] A?s Runs \[=\frac{35}{35+28+20}\times 581=245\] C?s Runs \[=\frac{20}{83}\times 581=140\] \[\therefore \] Difference between A's score and B's score = (245 - 140) = 105You need to login to perform this action.
