Explanation

Selling price = Cost + 10% profit

220 = Cost + 0.10 × Cost

220 = 1.10 × Cost

Cost = 220 / 1.10

= 200

Explanation

Assume cost price = 100

Marked price = 25% above CP:

$$100+25=125$$

Discount = 10% on 125:

$$10\%\text{ of }125=12.5$$

Selling price:

$$125-12.5=112.5$$

Profit

$$112.5 - 100 = 12.5$$

Explanation

Assume originally:

• Bought 100 items for Rs.100
  So, Cost Price (CP) per item = Rs.1

Now buys 10% less:

• 10% less than 100 = 90 items
• Still spends Rs.100

So new CP per item:

CP= 100/90​

Now sells 10% more:

• 10% more than 100 = 110 items

Assume selling rate is Rs.1 per item.

So total Selling Price:

$$SP=110\times 1=110$$

Profit:

$$Profit=SP-CP=110-100=10$$

Profit percentage formula:

$$\text{Profit \%}=$$Profit/ Cost Price ​×100

Substitute values:

10/100​×100=10%

That approach looks tempting, but it ignores that buying fewer changes the cost per item. The correct combined effect is:

Profit %=(110/90​−1)×100

$(110/90-1)\times 100$

$$=left(frac{20}{90}right)times100$$$$=22.22$$

Step 1: Find the cost of 1 apple

75/5​=15

Cost of 1 apple = Rs. 15

Step 2: Find the cost of 8 apples

$$8\times 15=120$$
