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

Explanation

Explanation

Let's denote the shares of Aslam, Khalid, and Salman as 2x, 3x, and 4x respectively.

Given Khalid's share = 3x = 600

x = 600 / 3 = 200

Aslam's share = 2x = 2 * 200 = 400

Explanation

Cost Price (CP) = Rs. 60

Selling Price (SP) = Rs. 90

Profit = SP - CP = Rs. 90 - Rs. 60 = Rs. 30

Profit percentage = (Profit / CP) * 100

= (30 / 60) * 100

= 50%

Explanation

Given the profit-sharing ratio:

Zubair : Kashif : Aijaz = 2 : 3 : 4

Kashif's share = Rs. 450

Let's find the value of one part of the ratio:

3 parts = Rs. 450

1 part = Rs. 450 / 3 = Rs. 150

Zubair's share = 2 parts

= 2 * Rs. 150

= Rs. 300

Explanation

Profit = 20% of Rs. 180 = 20/100 × 180 = 36

Selling Price = Cost Price + Profit = 180 + 36 = Rs. 216

Explanation

Let's denote the cost price as CP.

Given selling price (SP) = Rs 2400

Loss percentage = 20%

CP = SP / (1 - Loss percentage)

= 2400 / (1 - 0.20)

= 2400 / 0.80

= Rs 3000

Explanation

To find the cost price (CP) of the can of oil, we can use the formula:

CP = (Selling Price × 100) / (100 - Loss Percentage)

Given Selling Price (SP) = Rs. 7786 and Loss Percentage = 15%,

CP = (7786 × 100) / (100 - 15)

= (7786 × 100) / 85

= 7786 × 20 / 17

= 9160
