Question

A man purchased two tables at RS.600 each and another three tables RS.550 each . what is the average cost of tables​

Answer 1

Answer:

cost of two tables if 600₹ per table = 1200₹

cost of three tables if 550₹ per tables = 1650₹

$average \: cost \: of \: tables = \frac{1200 + 1650}{5}$

$= \frac{2850}{5}$

$= 570rs$

Answer 2

GIVEN:-

A man purchased two tables at RS.600 each and another three tables RS.550 each.

$\Large{\bf{\orange{\mathfrak{\dag{\underline{\underline{To \: Find:-}}}}}}}†$

Average cost of the tables

$\Large{\bf{\red{\mathfrak{\dag{\underline{\underline{Solution:-}}}}}}}†$

First,

The man purchased 2 tables at Rs. 660 each.

Now,

Cost of 2 tables =

Rs. 600 * 2

Rs. 1200

Second,

The man purchased 3 tables at Rs. 550 each.

Now,

Cost of 3 tables =

Rs. 550 * 3

Rs. 1,650

Now,

Average cost = ?

$\boxed{\pink{\sf Average \: cost \: = \: \dfrac{Total\: cost\: of\: the \:tables}{Number\: of \:tables \: 2 + 3</p><p>5}}}$

Substituting the values,

$\sf Average \: cost \: = \: \dfrac{Total\: cost \:of \:the\: tables}{Number \:of \:tables}$

$\sf Average \: cost \: = \: \dfrac{2850}{5}$

$\sf Average \: cost \: = \: \dfrac{\cancel{2850}}{\cancel{5}}$

$\sf Average \: cost \: = \: Rs. 570Averagecost</p><p>$

Therefore,

$\underline{\boxed{\therefore{\blue{\sf Average \: cost \: of \: the \: tables \: = \: Rs. \: 570.}}}}$
