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:

• The average cost of tables is Rs 570.

Step-by-step explanation:

Given that:

• A man purchased two tables at Rs. 600 each.
• Another three tables Rs. 550 each.

To Find:

• What is the average cost of tables?

Finding the total cost two tables:

• Cost of one table = Rs 600
• Cost of two tables = Rs(600 × 2) = Rs 1200

Finding the total cost another three tables:

• Cost of one table = Rs 550
• Cost of three tables = Rs(550 × 3) = Rs 1650

Formula used:

• Average cost = (Total Cost of tables)/(Number of tables)

Now we have:

• Total number of tables = 2 + 3 = 5
• Total cost = Rs(1200 + 1650) = Rs 2850

Finding the average cost of tables:

⟶ Average cost = 2850/5

⟶ Average cost = 570

∴ The average cost of tables = Rs 570

Answer 2

$\Large{\bf{\green{\mathfrak{\dag{\underline{\underline{Given:-}}}}}}}$

• 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 = ?

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

• Total cost of the tables =

• Rs. 1200 + Rs. 1650

• Rs. 2,850

• Total number of tables =

• 2 + 3

• 5

Substituting the values,

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

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

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

$\sf Average \: cost \: = \: Rs. 570$

Therefore,

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