Solution

The correct option is B Rs. 5000
Let cost price of car =x
Spent on repair =10% of cost price =10% of x=x10
Total cost =x+x10=11x10
Now, given that profit = Rs. 11000
And profit percentage =20%
profit×100Cost price=20
11000×10011x10=20
x=11000×100×1011×20=50000
Therefore, spent on repair =x10=5000010= Rs. 5000
