A man spends ` 500 in buying 12 tables and chairs. The cost of one table is ` 50 and that of one chair is ` 40. What is the ratio of the numbers of the chairs and tables purchased?
Answer
Answer (as printed):
Explanation
Let the number of tables purchased be x. Then, number of chairs purchased = (12 – x). \ 50x + 40 (12 – x) = 500 ⇔ 50x – 40x = 500 – 480 ⇔ 10x = 20 ⇔ x = 2. So, number of tables = 2 and number of chairs = 10. Hence, required ratio = 10 : 2 = 5 : 1.
