Given Information:
Ramu bought three articles - TV, washing machine, and AC. He paid a total of Rs 51,000 to the shopkeeper. The cost price of the washing machine is 20 percent less than that of the AC. The ratio of the cost price of the TV to the AC is 3:4.
Step 1: Determining the Cost Price of the TV, Washing Machine, and AC
Let's assume the cost price of the AC is x. According to the given ratio, the cost price of the TV will be (3/4)x.
Since the cost price of the washing machine is 20 percent less than that of the AC, the cost price of the washing machine will be (x - 20% of x) = (x - 0.2x) = 0.8x.
Therefore, the cost price of the TV, washing machine, and AC can be represented as follows:
TV: (3/4)x
Washing Machine: 0.8x
AC: x
Step 2: Determining the Selling Price and Profit
Ramu made a profit of 18 percent on selling the TV, 35 percent on selling the washing machine, and 22.5 percent on selling the AC.
Let's calculate the selling price of each article:
Selling Price of TV = Cost Price of TV + 18% of Cost Price of TV = (3/4)x + (18/100)(3/4)x = (3/4)x + (27/200)x = (9/8)x
Selling Price of Washing Machine = Cost Price of Washing Machine + 35% of Cost Price of Washing Machine = 0.8x + (35/100)(0.8x) = 0.8x + (28/100)x = (108/100)x
Selling Price of AC = Cost Price of AC + 22.5% of Cost Price of AC = x + (22.5/100)x = x + (9/40)x = (49/40)x
Step 3: Determining the Total Selling Price
The total selling price of all three articles is given as Rs 51,000.
Therefore, (9/8)x + (108/100)x + (49/40)x = 51,000
Step 4: Solving the Equation to Find the Value of x
Combining like terms, we get:
(72/64)x + (108/100)x + (49/40)x = 51,000
(180/160)x + (108/100)x + (49/40)x = 51,000
(180x + 172.8x + 196x)/160 = 51,000
(548.8x)/160 = 51,000
548.8x = 160 * 51,000
x = (160 * 51,000)/548.8
x ≈ 14,926.83
Therefore, the cost price of the AC is approximately Rs 14,926.83.
Step 5: Calculating the Cost Price of TV and Washing Machine
Using the ratio, the cost price of the TV can be calculated as:
Cost Price of TV = (
