A man purchased some tables at rupees 70 each and some chairs at rupees 45each .If total pieces of furniture purchased are 13 and their total cost is rupees 760 find how many tables and how many chairs did hi buy?

Answer 1

here is your answer

let the total number of table= x
total piece of chair = 13-x

cost of a table = 70 Rs
cost of x tables= 70x rs
cost of chair = 45rs
cost of 13-x chairs = 45×(13-x) = 585-45x

total cost = 70x + 585-45x = 760rs
25x + 585 = 760 Rs
25x = 760-585 = 175 Rs
x = 175/25 = 7

so total number of table = 7 tables
total no of chair = 13-x
13-7 = 6 chairs
