If the original price of a watch is Rs. 500 and it is increased by 10%, then decreased by 15%, what is the final price?

Correct option is B

Given:
Original price = Rs. 500, 10% increase, 15% decrease.
Formula Used:
Final price = P * (1 + r1/100) * (1 - r2/100)
Solution:
Final Price = 500 * (1 + 0.1) * (1 - 0.15) = Rs. 467.50.​
