Answer 1

Answer:

Step-by-step explanation:

1 chair price is 33.8 and 1 table price also 33.8

Then 21 chairs and 14 tables price is 35*33.8=1183

Answer 2

The cost price of 21 chairs and 14 tables is Rs. 1183.

Step-by-step explanation:

Since we have given that

Cost price of 12 chairs and 8 tables = Rs. 676

So, Let the price of chair be 'x'.

Let the price of table be 'y'.

According to question, it becomes,

$12x+8y=676\\\\4(3x+2y)=676\\\\3x+2y=\dfrac{676}{4}\\\\3x+2y=169$

We need to find the cost price of 21 chairs and 14 tables.

So, we get that

$7(3x+2y)=7\times 169=1183$

Hence, the cost price of 21 chairs and 14 tables is Rs. 1183.
