Answer:
Rs 200
Step-by-step explanation:
Let the C.P of each table = x
Let the C.P of each chair = y
4 tables + 5 Chairs = Rs 1000
4x + 5y = 1000 …….Eq(1)
10% profit on tables + 20% profit on chairs = Rs 120
(10/100) * 4x + (20/100) * 5y = 120
40x + 100y = 12000
2x + 5y = 600 ……..Eq(2)
Solving Eq(1) & Eq(2);
4x + 5y = 1000
2x + 5y = 600
(-) (-) (-)
——————— 2x = 400
=> x = 200
Therefore, the cost of 1 table = Rs x = Rs 200
