Show answer & explanation

Correct answer: A. 15,870

Explanation

Cost price = 14,400 ÷ 1.20 = Rs 12,000. New cost = 12,000 × 1.15 = Rs 13,800. New selling price = 13,800 × 1.15 = Rs 15,870.लागत मूल्य = 14,400 ÷ 1.20 = Rs 12,000। नई लागत = 12,000 × 1.15 = Rs 13,800। नया विक्रय मूल्य = 13,800 × 1.15 = Rs 15,870।
