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
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
