Explanation
Given:
10 pipes fill the tank in 1 hour 40 minutes = 100 minutes
Let's find the rate of 1 pipe:
Rate of 10 pipes = 1 tank / 100 minutes
Rate of 1 pipe = 1 tank / (10 × 100) minutes
= 1 tank / 1000 minutes
Rate of 8 pipes = 8 tanks / 1000 minutes
= 1 tank / (1000 / 8) minutes
= 1 tank / 125 minutes

Explanation
Given:Map scale = 1:250
Distance on map = 6 km
To find the actual distance, multiply the map distance by the scale factor:
Actual distance = 6 km × 250
= 1500 km

Explanation
Let's denote the smaller number as x and the larger number as x + 12.Given:
x + (x + 12) = 40
Combine like terms:
2x + 12 = 40
Subtract 12 from both sides:
2x = 28
Divide by 2:
x = 14
The larger number is x + 12 = 14 + 12 = 26
The numbers are 26 and 14.
- 50000x + 2500 = 75000
- 50000 + 2500x = 75000
- 50000x - 2500 = 75000
- None of these

Let's represent the situation with an equation:
Initial deposit = Rs. 50,000
Weekly deposit = Rs. 2,500
Target savings = Rs. 75,000
Let x be the number of weeks:
50,000 + 2,500x = 75,000

Explanation
The calculation is:log₂₄ 2^(1/2) = (1/2) / 4 = 1/8
Using the base-change identity:
logₐₙ aᵐ = m/n
Here, a = 2, m = 1/2, and n = 4:
log₂₄ 2^(1/2) = (1/2) / 4 = 1/8

اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Given:
Original length = 15 cm
Original area = 150 cm²
Original width = Area / Length
= 150 / 15
= 10 cm
New area = 1 1/3 times the original area
= 4/3 × 150
= 200 cm²
New length = New area / Width
= 200 / 10
= 20 cm
New perimeter = 2(Length + Width)
= 2(20 + 10)
= 2 × 30
= 60 cm
