Rajesh bought a motorcycle for rs.27000 and bought some accessories to make it look good. He sold the bike at a profit of 10% and at a selling price of 33000rs. How much did he spend on accessories?

Dear student,
Let he spend Rs x on extra fitting.
According to question,
Total money spend by him =27000+x
Now,
(27000+x)+ 10%(27000+x)= 33000
11/10(27000+x)=33000
x = 3000
So he spend 3000rs on accessories.
