Question

A man purchased some tables at 70rs each and some chairs at 45 each .If total pieces of furniture are 13 and there total cost is760.Find how many tables and chairs he purchased

Answer 1

Answer :

Lets suppose that number of tables purchased = n

Since total number of furnitures purchased is 13,

So number of chairs purchased = 13 - n

Cost of 1 table = 70 Rupees
=> Cost of n tables = (70 × n) Rupees

Cost of 1 chair = 45 Rupees
=> Cost of (13 - n) chairs = 45 × (13 - n) Rupees

So total cost = (70 × n) + (45 × (13-n))

According to the question,

760 = 70n + 585 - 45n

=> 760 = 25n + 585

=> 25n = 760 - 585

=> 25n = 175

=> n = 7

●So total number of tables purchased = n = 7

●So total number of chairs purchased = 13-n = 6.
