Question 58
A carpenter bought a rectangular white board of dimension 4 feet x 3 feet, which cost him Rs 12 per square feet.The cost of fixing aluminum lining to all the edges was Rs 4 per feet.At what price should he sell the finished white board so as to gain 25% on the cost price ?
Solution
The cost of the board = 4x3x12= 144
Cost of the aluminium lining = (4+4+3+3)x4 = 56
So total cost = 200 Rs
Selling price = 200 x 1.25 = 250 Rs
