Question 7

Vishnu spends ₹ 5000 in buying 12 tables and some 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 to the number of tables purchased?

Solution

Cost of 12 tables= $$12\times 50$$ = Rs.600 (cost of 1 table= Rs.50 )

Cost of chairs= 5000- 600= 4400

In Rs. 40 =1 chair

In Rs. 4400= $$4400\div 40= 110$$

Ratio of the number of the tables to the numbers of chairs purchased= 12:110 = 6:55

Hence the required ratio = 55:6
