Question

The total cost of both a chair and a table is 2800. If the cost of the chair is 40% less than the table price then tell the price of the chair

Answer 1

let the price of table is X
now,
=X+X×60%=2800
=X+60X/100=28
$\frac{100x + 60x}{100} = 2800$
=160X=2800×100
X=2800×100/160
=1750
Price of chair=1750×60%
=1750×60/100
=1050

Answer 2

Cost price of chair is Rs.1050/-

Step-by-step explanation:

Suppose that,

The cost price of table is Rs.100/-

And the cost price of the chair is less than 40 % of the table price ,

Then, cost price of chairs is Rs.60/-

According to the questions,

100 + 60 = 2800

160 = 2800

Or,

1 = $\frac{2800}{160}$

1 = 17.5

Thus, cost price of chair = $60\times 17.5$

= 1050

Cost price of table = $17.5\times 100$

= Rs.1750

Cost price of chair is Rs.1050/-
