Question

The price of the entrance ticket to a park is ₹205. If 195 people visit the park on a public holiday, find the total amount of money obtained by selling tickets that day.

• A. ₹39,775
• B. ₹38,975
• C. ₹39,757
• D. ₹39,975

Answer 1

The correct option is D ₹39,975

Cost of the entrance ticket of a park = ₹205

Number of people visited the park on the public holiday = 195

Total money obtained $=205\times 195$
$=(200+5)\times (200-5)$

[using $(x+y)(x-y)=x^2-y^2$]

$={200}^2-5^2=40000-25=39975$

Therefore, the total money obtained is ₹39,975.

The correct option is D.
