What was the approximate percent drop in the sales of pep-up in 1990 over its sale in 1989?

Answer: Option B

Sales of pep up:
Year 1989 = 35 lakh bottles
Year 1990 = 30 lakh bottles
∴ Required percent
$$\begin{array}{rl}& =\frac{35-30}{35}\times 100\\ & =\frac{100}{7}\\ & =14.28\approx 14\end{array}$$
