Question

If watches bought at prices ranging from Rs. $200$ to Rs. $350$ are sold at prices ranging from Rs. $300$ to Rs.$425$. What is the greatest possible profit that might be made in selling nine watches ?

Answer 1

Profit would be maximum if watches are brought for Rs.$200$ and sold for Rs. $425$
Profit $=$ Rs. $(425-200)=$ Rs.$225$
Profit of $9$ watches $=$ Rs. $225\times 9=$ Rs.$2,025$.
