Q77 2014, Profit, Loss and Discount

For a charity show, the total tickets sold were 420. Half of these tickets were sold at the rate of ₹5 each, one-third at the rate of ₹3 each and the rest for ₹2 each. What was the total amount received ?

किसी चैरिटी शो के लिए, कुल 420 टिकटें बिकीं । इन टिकटों में आधी प्रत्येक ₹5 की दर पर, एक-तिहाई प्रत्येक ₹3 की दर पर और शेष टिकटें प्रत्येक ₹2 की दर पर बिकीं । कुल प्राप्त धनराशि कितनी थी?

Explanation Please wait..

Total number of tickets = 420

Tickets sold at Rs. 5 = 420/2 = 210

Tickets sold at Rs. 3 = 420/3 = 140

Remaining tickets sold at Rs. 2 = 420 - (210 + 140)

= 420 - 350= 70 tickets

Now, total amount received = (210 x 5) + (140 x 3) + (70 x 2)

=1050 + 420 + 140= 1610

Hence, option (c) is correct,
