Explanation

Cost Price (CP) = Rs. 800
Selling Price (SP) = Rs. 1,000

Gain = SP − CP

$$=1000-800=200$$

Gain % = (Gain ÷ CP) × 100

$$=$$200/800​×100

=25%

Explanation

Given:

• Selling Price (SP) = Rs. 1,200
• Profit = 7%

Formula:

SP=CP×107/100

CP=1200×100/107

CP=1121.50

Explanation

Formula: Amount = Principal _ (1 + r/100)^n

Given:

Amount = 1.44 _ Principal

n = 2 years

Put values:

1.44 _ P = P _ (1 + r/100)^2

Cancel P from both sides:

(1 + r/100)^2 = 1.44

Take square root both sides:

1 + r/100 = 1.2

r/100 = 1.2 - 1 = 0.2

r = 0.2 * 100 = 20

Explanation

Purchase price = Rs. 23800  

Profit = 6%

Sale price = Purchase price + Profit  

= 23800 + (6% of 23800)  

= 23800 + (0.06 × 23800)  

= 23800 + 1428  

= Rs. 25228

Explanation

Given:

• Profit = Rs. 120
• Profit = 20% of Selling Price (SP)

20% of SP=120
SP=120×100/20​=Rs.600

Now,

$$CP=SP-Profit$$

$$=600-120$$

$$=Rs.480$$

Explanation

Selling Price = Rs. 120
Profit = 20%

$$CP=$$SP×100​ /100+20=120120×100​

=Rs.100

Explanation

Profit is divided according to Capital × Time.

• A = $20,000 times 24 = 480,000$
• B = $15,000 times 24 = 360,000$
• C = $20,000 times 18 = 360,000$

Ratio:

$$480000:360000:360000=4:3:3$$

Total parts:

$$4+3+3=10$$

B's share:

3/10×25,000=7,500

Explanation

5% of Rs. 1,200 = Rs. 60

Remaining amount = Rs. 1,200 − Rs. 60 = Rs. 1,140.

Explanation

Selling price = Cost + 10% profit

220 = Cost + 0.10 × Cost

220 = 1.10 × Cost

Cost = 220 / 1.10

= 200
