A block and tackle system has V.R. = 5.
Rohan exerts a pull of 150 kgf. What is the maximum load he can raise with this pulley system if its efficiency = 75% ?

Explanation

To solve the problem step by step, we will follow the given information and apply the relevant formulas.

### Step 1: Understand the given values
- Velocity Ratio (V.R.) = 5
- Effort exerted by Rohan = 150 kgf
- Efficiency (η) = 75% = 0.75

### Step 2: Relate Efficiency, Mechanical Advantage (MA), and Velocity Ratio (V.R.)
