mr sehgal buys 4 chairs and 5 tables for 3400 later he buys another chair and 4 tables more of same type for 2500 rs find cost of each chair and each table ​

Answer 1

Answer:

Hi friend,

Let the cost of 1 chair and 1 table be X and Y.

According to question,

5X+4Y = 2800......(1)

And,

4X +3Y = 2170......(2)

Multiply equation (1) and (2) by 4 and 5 .

5X +4Y = 2800.......(×4)

4X +3Y = 2170........(×5)

Equation (1) and (2) becomes ,

20X + 16Y = 11200......(4)

+20X + 15Y = 10850......(5)

0 + Y = 350

Therefore,

5X + 4Y = 11200

5X +4 × 350 = 11200

5X = 11200-1400

5X = 9800

X = 9800/5

X = 1960

Hence,

The cost of a chair = X = Rs 1960

And,

A table = 350
