Answer 2

$\mathfrak{\large{\underline{\underline{Answer :-}}}}$

The cost of Table is Rs. 500 and Chair is Rs. 250.

$\mathfrak{\large{\underline{\underline{Explanation :-}}}}$

Given :

Cost of table is twice the cost of chair

Both cost together = Rs. 750

To Find :

Cost of table and chair

Solution :

Consider the cost of chair as x

Table's Cost = 2x

★ $\boxed{\sf{x+2x=750}}$

$\sf{\implies} \: x + 2x = 750$

$\sf{\implies} \: 3x = 750$

$\sf{\implies} \: x = \dfrac{750}{3}$

$\sf{\implies} \: x = 250$

Chair = Rs. 250

$\rule{300}{1.5}$

★ Value of 2x

$\sf{\implies} \: 2 \times 250$

$\sf{\implies} \: 500$

Table = Rs. 500

$\therefore$ The cost of Table is Rs. 500 and Chair is Rs. 250.

$\rule{300}{1.5}$

$\mathfrak{\large{\underline{\underline{Verification :-}}}}$

$\sf{\implies} \: 250 + (2 \times 250) = 750$

$\sf{\implies} \: 250 + 500 = 750$

$\sf{\implies} \: 750 = 750$

$\therefore$ The cost of Table is Rs. 500 and Chair is Rs. 250.
