Solution
The correct option is C Decreased
Let x=10%
Let initially cotton was 100.
After first increment it become
10===10% up ==110
Second increment,
110===10% up ==121
First Decrement,
121==10% down ==108.9
Second decrement,
108.9==10% down ==98.01
See, initially it was 100 now become 98. it means decreases.
