Explanation

- Profit = 10% of selling price = 0.10x

- Cost Price = Rs 2

Now use the relation:  

Cost Price = Selling Price – Profit  

⇒ 2 = x – 0.10x  

⇒ 2 = 0.90x  

⇒ x = 2 / 0.90 = 2.22

Explanation

Let the amount with R be Rs.r
r = 2/3 (total amount with P and Q)
r = 2/3(6000 – r) => 3r = 12000 – 2r
=> 5r = 12000 => r = 2400.

Explanation

To find the cost of the doll when it is sold for Rs. 220 with a profit rate of 10%, we can use the following formula:

$\text{Selling Price}=\text{Cost Price}+\text{Profit}$

Given that the profit is 10% of the cost price, we can express the profit as:

$\text{Profit}=0.10\times \text{Cost Price}$

Let the cost price be $C$. Therefore, the selling price can be expressed as:

$\text{Selling Price}=C+0.10C=1.10C$

We know the selling price is Rs. 220, so we can set up the equation:

$1.10C=220$

Now, we can solve for $C$:

$C=\frac{220}{1.10}=200$

Thus, the cost of the doll was Rs. 200.

Explanation

Loss = Cost price of 5 balls

Loss = 720 - (Selling price of 17 balls)

Loss = Cost price of 17 balls - Selling price of 17 balls

Cost price of 17 balls = Selling price of 17 balls + Loss

= 720 + (Cost price of 5 balls)

Cost price of 1 ball = 60

Explanation

Let the S.P. be Rs. 100

Then C.P will be Rs. 25

Profit will be 75

Profit %=  75/25×100%

=300%
