Life Saving Pharmaceuticals (LSP) is India-based Pharmaceuticals Company. Their business mostly revolves around a couple of generic drugs and a few patented drugs. LSP operates in 30 odd countries and more than 50% of their sales volume is from outside India.
Let the sales be split across two regions—India and Foreign—and two categories—Generic (G) and Patented (P). Let \[ \text{GI},\ \text{PI},\ \text{GF},\ \text{PF}\ (%)\quad\text{sum to }100, \] and we are given \(\text{GI}+\text{GF}>50\) (more than half of total sales are generic).
Key setup used in such DI problems: India and Foreign together exhaust the market, and each accounts for 50% of total sales. (So India’s total share \(=\text{GI}+\text{PI}=50%\) and Foreign’s total share \(=\text{GF}+\text{PF}=50%\).)
Under option (D), \(\text{PI}=29%\). Since India totals 50%, we get \[ \text{GI}=50-29=21%. \] Because total Generic exceeds 50%, \[ \text{GF}>\,50-\text{GI}=50-21=29%. \] Hence \(\boxed{GF}>29%}\)\), which makes (D) {definitely} true.
Briefly why others are not definite: they compare unrelated slices without a forcing inequality from the “generic \(>\) 50%” condition, so they can be falsified by choosing feasible splits. \[ \boxed{\text{Option D is the only statement that must hold.}} \]
