Explanation

To calculate the selling price after a 3% loss, use the formula:

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

= 500 × (1 - 0.03)  

= 500 × 0.97 = Rs. 485

Explanation

- Cost of 1 egg = 60 ÷ 9 = Rs. 6.67

- Cost of 3 eggs = 6.67 × 3

= Rs. 20

Explanation

Profit = Selling Price − Cost Price  

= 11,000 − 10,000 = 1,000

Profit % = (Profit / Cost Price) × 100  

= (1,000 / 10,000) × 100 = 10%

Explanation

 - Price of 1 dozen eggs = 12 rupees  

- Price of 1 egg = 12 / 12 = 1 rupee  

- Number of eggs in 2.5 dozen = 2.5 × 12 = 30 eggs  

- Price of 30 eggs = 30 × 1 = 30 rupees  

Explanation

Calculating the Markup (Interest)

Interest = Principal × Rate × Time

= 70000 × 0.07 × 3

= 70000 × 0.21

= 14700

Explanation

We have pairs of letters:

• AA (A repeated twice) — Z

• BB (B repeated twice) — Y

• CC (C repeated twice) — X

• D _

It seems like:

• First letter is moving forward: A → B → C → D

• Second letter is moving backward from Z: Z → Y → X → W

So after D, we should have W.

Explanation

Cost Price (CP) = ₹60  

Profit = 20%

Selling Price (SP) = CP × (1 + Profit%)  

SP = ₹60 × (1 + 20/100)  

SP = ₹60 × 1.20 = ₹72

Explanation

Given:  

Cost of 5 pencils = ₹10  

So, Cost Price (CP) of 1 pencil = ₹10 ÷ 5 = ₹2

Loss = 10%

Now,  

Selling Price (SP) = CP × (1 - Loss%)  

SP = ₹2 × (1 - 10/100)  

SP = ₹2 × 0.90 = ₹1.80 per pencil

Total SP for 5 pencils = 5 × ₹1.80 = ₹9.00

Explanation

Let us consider that the actual cost of the article is "x".

Since the decrease in price = 24 %= 0.24

x - 0.24 x = 912

0.76 x = 912

x = 912 / 0.76

x = 1200

Explanation

Step 1: Find total work done.  

10 men × 4 days = 40 man-days  

They earn = 500 units

So, per man-day earning = 500 ÷ 40 = 12.5 units

Step 2: Calculate earning for 8 men in 6 days:  

8 men × 6 days = 48 man-days

So, 48 man-days × 12.5 units = 600 units
