Question

एक मेले में किसी दिन 35000 दर्शक पहुचे तथा उनसे रु 950000 प्रवेश राशी प्राप्त की गई. यदि प्रवेश शुल्क वयस्क के लिए रु 40 तथा बच्चे के लिए रु 20 हो तथा 10% दर्शको को निशुल्क पास मिला हो, तो मेले में कितने बच्चे थे?

Answer 1

Answer with explanation:

Total number of visitors who went for Fair= 35000

Visitors who has got free pass=10%

So, 10% of 35000

  $=\frac{10}{100}\times 35000\\\\=3500$

Number of Visitors who have paid money to enter inside the Fair

     =35000 -3500

     =31,500

Let number of children = x

Then , number of Adults=31500 -x

Total Amount Obtained on a Particular Day when 35,000 visitors visited the fair = Rs 950000

⇒40× (31500 -x)+20× x=950000

⇒1260000-40 x+20 x=950000

⇒20 x=1260000 -950000

⇒ 20 x= 310000

Dividing both sides by 20, we get

x=15500

Number of Children =15,500

Then , number of Adults=31,500 - 15,500

         =16,000
