Question

A food vendor sells 60 tacos every day. If the sales increase by 10 percent during the festival season, then how many tacos will he sell in one day during the festival?

• A. 70
• B. 76
• C. 65
• D. 66

Answer 1

The correct option is D 66

Number of tacos sold by the vendor every day $=60$
Increase in percentage of sales during festival season $=10\%$
Increased sale $=10\%\text{of}60=\frac{10}{100}\times 60=6$
Number of tacos food vendors sell during the festival days $=60+10\%\text{of}60$
$=60+6=66$ tacos
