Question

2. A gardener buys saplings from a nursery at 12 a
score and sells them at 78.40 for 10. What is his gan
per cent? ( score = 20)​

Answer 1

Answer is 40%

Given ,

• Score = 20
• C.P of 20 rupees = 12
• S.P = 8.40

Solution ,

In the same way, now let us try for 1 rupees

• C.P of 1 piece = 12/20

Let us try for 10 rupees

• C.P of 10 piece = 12 /20×10
• Now divide it by 2
• We get 6

We know that,

Gain = SP - CP

⇒ 8.40 - 6.00

⇒ 2.40

Now let us convert it into percentage

We know that,

Gain percentage = P/CP × 100

⇒ 2.40/6×100

⇒ 0.40 × 100

⇒ 40%

Answer 2

Answer:

The answer is 40 % ..............
