Answer 2

Answer:

Loss of 4%

Step-by-step explanation:

Find the total selling price:

1 machine = Rs 2400

2 machines = 2400 x 2 = Rs 4800

Find the cost price of one machine:

Gain = 20%

Selling Price = 100 + 20 = 120%

120% = Rs 2400

1% = 2400 ÷ 120 = Rs 20

100% = 20 x 100 = Rs 2000

Find the cost price of the other machine:

Loss = 20%

Selling Price = 100 - 20 = 80%

80% = Rs 2400

1% = 2400 ÷ 80 = Rs 30

100% = 30 x 100 = Rs 3000

Find the total cost price:

Total cost price = 2000 + 3000 = Rs 5000

Find the gain /loss:

Rs 5000 > Rs 4800 ⇒ Loss

Loss = 5000 - 4800 = Rs 200

Find the loss percentage:

Loss = loss/cost price x 100

Loss = 200/5000 x 100 = 4%

Answer: The loss is 4%
