a) 171
b) 181
c) 185
d) 161
Answer: a
Explanation: Given total runs of A, B, C
(A + B + C = 361)
$$\eqalign{
& \Rightarrow {\text{A}}:{\text{B}}:{\text{C}} \cr
& \,\,\,\,\,\,\,\,\,3:2 \cr
& \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,3:2 \cr
& \underline {\overline {\,\,\,\,\,\,\,\,\,\,9:6:4{\text{ }}} } \cr
& 9x + 6x + 4x = 361 \cr
& \Rightarrow 19x = 361 \cr
& \Rightarrow x = 19 \cr
& {\text{Runs scored by A }} = 9x \cr
& = 9 \times 19 \cr
& = 171 \cr} $$
