Answer:
Total cost price of two laptops is 78000. The profit on one laptop is 20% and loss on the other laptop is 15%. The total selling price of two laptops is Rs. 78900. The ratio of cost price of two laptops is 7:6
Step-by-step explanation:
Let x be the cost price of one laptop.
The cost price of the other laptop is given by:
= 78000 - x
Let's assume the first laptop is sold at a profit of 20%.
The selling price = 1.20x
The selling price of the second laptop = 0.85 (78000 - x)
= 66300 - 0.85x
The sum of their selling price is:
1.20 x + 66300 - 0.85 x = 78900
0.35 x + 66300 =78900
0.35 x = 78900 - 66300
0.35 x = 12600
x = 12600/0.35 = Rs 36000
The cost price of the other laptop is:
78000 - 36000 = 42000
The ratio of the cost price of the laptops is:
42000/36000 = 7/6
The ratio is 7:6
