Explanation

• Let the cost price (CP) = 100 (for easy calculation)

• Selling price (SP) = triple the CP = 3 × 100 = 300

Profit = SP − CP = 300 − 100 = 200

Profit Percentage = (Profit ÷ Cost Price) × 100
= (200 ÷ 100) × 100
= 200%

Explanation

40% of 30

= (40/100) × 30

= 12

Selling Price: 30 + 12

= 42

Question updated 03-March-2026

Explanation

Profit = Selling Price - Cost Price

= 390 - 300 = 90
Profit % = (Profit / Cost Price) × 100

= (90 / 300) × 100 = 30%

Explanation

Cost price = $30

Profit % = 30%

Profit = 30% of 30 = 0.3 × 30 = $9

Selling price = Cost price + Profit = 30 + 9 = $39

Explanation

 profit/cost price*100

10/30*100=33.33.....%

Explanation

1. Cost Price (CP) = 500

2. Selling Price (SP) = 600

3. Profit = SP – CP

$$Profit=600–500=100$$

4. Profit Percent = (Profit ÷ CP) × 100

$$Profit\%=(100÷500)\times 100=20\%$$

Answer:

• Profit = Rs. 100

• Profit Percent = 20%

Explanation

If 15 pencils cost 175,  

Cost of 1 pencil = 175 ÷ 15 = 11.67 (approx)

Cost of 12 pencils = 11.67 × 12 = 140

Explanation

Cost of 25 toys = 500

Cost of 01 toys = 500/ 25 = 20/ 1

1 toys = 20 

Cost f 75 toys = 75 x 20 = 1500

Explanation

To find the purchase price, use the formula:

Selling Price = Purchase Price × (1 - Loss%)

Given:  

Selling Price = Rs. 25,000  

Loss = 20% → (1 - 0.20) = 0.80

Now,

25,000 = Purchase Price × 0.80  

Purchase Price = 25,000 ÷ 0.80 = Rs. 31,250

Explanation

Total books = 65 + 50 = 115  

Total cost = 1150 + 920 = Rs. 2070  

Average price per book = 2070 ÷ 115 = Rs. 18
