Raman took three different bags made up of three different materials P, Q and R. He put 10 kg of onions in each bag. Bag Q bursted immediately, bag P carried the weight for a few minutes and then bursted while bag R remained intact. Materials P, Q and R could be respectively

Options

A. Wool, silk and cotton
B. Nylon, rayon and silk
C. cotton , Silk and nylon
D. Cotton, nylon and silk

Explanation

To solve the question about the materials of the bags P, Q, and R based on their performance under weight, we can follow these steps:

### Step 1: Analyze the performance of each bag
- Bag Q burst immediately, indicating that it has the least tensile strength.
- Bag P carried the weight for a few minutes before bursting, suggesting it has moderate tensile strength.
- Bag R remained intact under the weight, indicating it has the highest tensile strength.

### Step 2: Understand tensile strength in materials
- Tensile strength refers to the maximum amount of tensile (pulling) stress that a material can withstand before failure.
- Synthetic fibers generally have higher tensile strength compared to natural fibers.

### Step 3: Identify the materials based on their tensile strength
- Since bag R remained intact, it must be made of a synthetic fiber with high tensile strength. The most common synthetic fiber known for high tensile strength is nylon.
- Bag P, which burst after a few minutes, likely has a moderate tensile strength. Among natural fibers, cotton is known to have a higher tensile strength than silk.
- Bag Q burst immediately, indicating it has the lowest tensile strength. Silk is a natural fiber that is weaker compared to cotton and nylon.

### Step 4: Assign materials to bags
- Bag R = Nylon (highest tensile strength)
- Bag P = Cotton (moderate tensile strength)
- Bag Q = Silk (lowest tensile strength)

### Conclusion
Thus, the materials of the bags P, Q, and R can be identified as:
- Bag P: Cotton
- Bag Q: Silk
- Bag R: Nylon

### Final Answer
The materials P, Q, and R could be respectively: Cotton, Silk, Nylon.
