John bought a car for a certain sum of money. He spent 10% of the cost to repairs and sold the car for a profit of Rs. 11000. How much did he spend on repairs if he made a profit of 20%?

r =  5000 Rs

Solution:

q=10%=10100=0.1 p=20%=20100=0.2    11000=p a 11000=0.2 a  0.2a=11000  a=55000    a=x+q x 54999.9999998=x+0.1 x  1.1x=55000  x=50000  r=q x=0.1 50000=5000 Rs
