What is the total expenditure if Ahmed buys a watch for Rs 600 subject to a 15% sales tax?
Show answer Hide answer
Answer: D. 690
Explanation
Ahmed purchases a watch with a base list price of six hundred currency units. A fifteen percent sales tax is calculated by multiplying the watch price by zero point one five. Adding the computed sales tax amount to the base price yields a total expenditure of six ninety. Sales tax calculations involve applying a percentage markup to the base retail cost of a consumer item. Multiplying a base price by one plus the tax rate decimal computes the final gross purchase total directly. Financial transactions require adding indirect taxes to determine the exact cash outlay required by buyers.
Retail point of sale systems calculate applicable sales taxes automatically during customer checkout transactions. Consumer budgeting requires factoring local sales tax rates into the final cost of everyday purchases. Tax authorities establish statutory percentage rates that merchants must collect on taxable retail goods. Option A underestimates the final total expenditure by calculating an incorrect tax percentage value. Option B represents an intermediate arithmetic result that fails to match the exact tax computation. Option C results from an arithmetic miscalculation during the addition of the tax amount.
