Question

3chairs and 2 tables cost is 700 while 5 chaits and 3 tables rs 1100 what is the cost of 2 chairs and 1 table

Answer 1

Answer:

400

Explanation:

3c+2t = 700......(1)

5c+3t = 1100.....(2)

if we multiply (1) with 3 & (2) with 2 then

9c+6t = 2100

10c+6t = 2200

-. -. -. if we substrate 1 from 2

-1c+0. = -100. cancel both minus then

1c=₹100/-

if we put this in (1) then

3(100)+2t = 700

2t= 700-300

2t = 400

then 1t = 200

we want prices of 2chair and 1 table

1chair cost is 100

2 chairs cost is 200

1 table cost is 200

total ₹400/-
