QUESTION: 5
The price of 3 table-fans and 3 ceiling-fans is Rs 4,350.If the cost of 2 ceiling-fans and 1 table-fan is Rs 2,250,what is the cost of one ceiling fan?
Solution: Let price of one table fan = Rs x
and price of one ceiling fan = Rs y
So 3x + 3y = 4350 .....(1)
x + 2y = 2250 .....(2)
Multiplying 2 in equation (1) and 6 in equation (2) we get
6x + 6y = 8700 .....(3)
6x + 12y = 13500 .....(4)
Subtracting equation (3) from equation (4) we get
6y = 4800
⇒ y = 800
So cost of one ceiling fan Rs 800
