Venkat bought a second-hand scooter and spent 10% of the cost on its repairs. He sold the scooter for a profit of Rs. 2,200. How much did he spend on repairs if he made a profit of 20%?

Correct option is C

​$$20\% = \frac{2200}{\text{CP}} \times 100$$​​

​$$\text{CP} = \frac{2200 \times 100}{20} = 11000$$​​
