0 votes 0 votes $18\%-12\% \implies \text{₹}18$ $6\% \implies \text{₹}18$ $1\% \implies \text{₹}3$ Now, $100\% \implies \text{₹}300.$ So, the correct answer is $(B).$ Lakshman Bhaiya answered Sep 11, 2020 Lakshman Bhaiya 13.8k points comment Share See all 0 reply Please log in or register to add a comment.
