एक वयस्क के टिकट का मुल्य 500 है और एक बच्चे के टिकट का मुल्य 200 है। दो वयस्कों के साथ 1 बच्चा निशुल्क जा सकता है। यदि किसी समूह में 20 वयस्क और 8 बच्चे हैं, तो समूह को कितनी छूट मिलेगी?
A)
53.43 %
B)
13.79 %
C)
32.2 %
D)
35.06 %
Correct Answer :
13.79%
Explanation :
Total Price of the ticket without discount = (20*500 + 200 *8)=11600
Total Price of ticket with discount = (20*500) = 10000
Total discount % = (11600-10000)*100/11600 = 13.79%
Let the original selling price of mobile is x.
As is given,
x - (25/100) * x = 4875
x - x/4 = 4875
3x/4 = 4875
x = 4875*4 /3 = 6500
Hence, original selling price of mobile is 6500.
Let MP of Pepsi be P and Coke be C.
P after two successive discounts = 90/100 * 75/100 * P
C after two successive discounts = 85/100 * 80/100 * C
therefore ratio or price , 90/100 * 75/100 * P = 85/100 * 80/100 * C
P/C = 85 * 80 / 90 * 75 => 17 * 8 / 9 * 15
P/C =136/135
Let original price = Rs. 100
Price after 1 st discount = Rs. 90
Price after 2 nd discount = Rs. (80/100) x 90 = Rs. 72
Price after 3 rd discount = Rs. (60/100) x 72 = Rs. 43.20
