A batsman scored 110 runs which included 3 boundaries and 8 sixes. What percent of his total score did he make by running between the wickets ?

Answer: Option B

Number of runs made by running
= 110 - (3 × 4 + 8 × 6)
= 50
∴ Required percentage :
$$\begin{array}{rl}& =\left(\frac{50}{110}\times 100\right)\%\\ & =45\frac{5}{11}\%\end{array}$$
