Suneel bought a scooter for a certain sum of money. He spent 10% of the cost on repairs and sold the scooter for a profit of Rs. 1100. How much did he spend on repairs if he made a profit of 20% ?

\par Let the C.P. be Rs. x. Then, 20\% of x = \par 1100

\frac{20}{100}$ $\times x \par = 1100

\par x = 5500

\par C.P. = 5500, \par Expenditures on repairs = 10\%

\par Actual price = Rs. \left(\frac{100}{110}\times 5500\right) = \par Rs. 5000

\par Expenditure on repairs = Rs. (5500 - 5000) = Rs. 500
