Sidhartha has decided to start a new company ‘Siddharth Travels’. He wants to buy some furniture – table, chair, air-conditioners. He also wants to buy a few desktops which will include monitor, CPU, keyboard and mouse and the cost of each table is 13.5 times the cost of a mouse and the cost of chair is 3/5 of the cost of a table. The cost of an air conditioner is 5 times the cost of a chair. The cost of a monitor is 20% more than the cost of a chair, A CPU costs Rs. 1500 more than a table and the keyboard costs 4 times a mouse. The cost of a mouse is Rs. 1000.
It was initially decided that 4 air conditioners will be installed but later only 3 air conditioners and a fan were installed. If the cost of a fan is 1/10 of the costs of an air conditioner, what was the total cost incurred?
Solution
Cost of a mouse is ₹ 1000.
Cost of a keyboard = ₹ 1000 $\times$ 4 = ₹ 4000
Cost of a table = ₹ 1000 $\times$ 13.5 = ₹ 13500
Cost of a chair = $\dfrac{3}{5} \times$ 13500 = ₹ 8100
Cost of an air conditioner = 5 $\times$ 8100 = ₹ 40500
Cost of a fan = 40500 $\times \dfrac {1}{10}$ = 4050
Now, the cost of 3 air conditioners + 1 fan = 3 $\times$ 40500 + 4050 = 121500 + 4050 = ₹ 125550.
