Explanation

Depreciation formula: 

Value after n years = Original Price x (1 - rate)^n

Given:

Original Price = Rs. 76000

Rate = 20% = 0.20 per year

Time = 2 years

Value after 2 years = 76000 x (1 - 0.20)^2

= 76000 x (0.80)^2

= 76000 x 0.64

= Rs. 48640

Explanation

5% of y = 40

5/100 x y = 40

0.05 x y = 40

y = 40 / 0.05

y = 800

Explanation

Zakat rate in Islam = 2.5% of total assets

Given 

Zakat paid = Rs. 4200

Formula:

Zakat = 2.5% of Total Assets

4200 = 2.5/100 x Total Assets

Total Assets = 4200 x 100 / 2.5

Total Assets = 420000 / 2.5

Total Assets = Rs. 168000

Explanation

Total marks = 1100

Percentage obtained = 65%

Marks obtained = 65% of 1100

Marks obtained = (65 / 100) x 1100

Marks obtained = 0.65 x 1100

Marks obtained = 715

Explanation

In Islam, Zakat is usually 2.5% of the wealth if it has been held for one lunar year and meets the nisab.

Given amount: Rs. 28560

Zakat = 2.5% of 28560  

= (2.5 / 100) × 28560  

= 0.025 × 28560  

= Rs. 714

Explanation

Given:

• Dividend (D₀) = Rs. 4
• Market Price (P₀) = Rs. 100
• Growth rate (g) = 5%

Step 1: Calculate next year’s dividend

D₁ = D₀ × (1 + g)
= 4 × 1.05
= Rs. 4.20

Step 2: Use the Gordon Growth Model

Required Return:

Ke​=D1/P0​​​+g 

Ke​=4.20/100 ​+0.05

Ke​=0.042+0.05=0.092

Ke​=9.2%≈9%

Explanation

For an ordinary annuity:

PV=PMT×1−(1+r)−n/r​

PMT = Rs. 4,000

r = 8% = 0.08

n = 20 years

PV ≈ Rs. 39,727

Explanation

25 = 125% of x

To convert the percentage to a decimal, divide by 100:

25 = 1.25x

Now, divide both sides by 1.25 to solve for x:

x = 25 / 1.25

x = 20

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

Original salary = Rs. 50,000

Increase = 20% of 50,000

20/100​×50,000=10,000

New salary:

$$50,000+10,000=60,000$$
