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
No answer key was printed for this question.
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.
