Question

a lady buys some pencils for rupees 3 and an equal number for rupees 6.She sells them for rupees 7. find the gain or loss percent

Answer 1

Answer:

55.6%

Step-by-step explanation:

Let the number of pencils bought the first time be x

Cost of pencils bought at Rs 3:

1 pencil = Rs 3

x pencils = Rs 3x

⇒ x pencils cost Rs 3x

Cost of the pencils bought at Rs 6

1 pencil = Rs 6

x pencils = Rs 6x

⇒ x pencils cost Rs 6x

Find the total cost:

Total cost = 3x + 6x = 9x

⇒ 2x pencils cost Rs 9x

Find the total selling price:

1 pencil = Rs 7

2x pencil = (2x)(7) = 14x

⇒ 2x pencils cost Rs 14x

Find the gain or loss:

Gain = Selling Price - Cost Price

Gain = 14x - 9x = 5x

Gain percentage = gain/cost price x 100

Gain percentage = (5x ÷ 9x) x 100 = 55.6%

Answer: There is a gain of 55.6%
