A) 6300

B) 6400

C) 6500

D) 6600

Correct Answer : 35

Explanation : Let the original selling price of mobile is x.
As is given,
x - (25/100) * x = 4875

x = 4875*4 /3 = 6500
Hence, original selling price of mobile is 6500.

Ticket for an adult is 500 and a child is 200. 1 child goes free with two adults. If a group has 20 adults and 8 children what will be the discount the group get?

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%

A) 143 : 144

B) 19 : 11

C) 136 : 135

D) 73 : 77

Correct Answer : 136 : 135

Explanation : 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

A discount series of 10%, 20% and 40% is equal to single discount of ?

10%, 20% और 40% की क्रंमबद्ध छूट, एकल छूट के बराबर होगी?

A) 50%

B) 56.80%

C) 70%

D) 70.28%

Correct Answer : 56.80%

Explanation : 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
Thus, overall discount = (100 - 43.20) = 56.8%

Successive discount of 10% and 10% are equivalent to a single discount of ?

10% और 10% की क्रंमबद्ध छूट, एक ही छूट के बराबर होगी?

A) 19%

B) 21%

C) 21%

D) 18%

Correct Answer : 19%

Explanation : Let the CP be 100. Then,
SP = 90% of 90% of 100
= (90/100)*(90/100)*100
= 81

Single discount = (100-81)% = 19%

A retailer buys a washing machine marked at Rs 4800 and gets two successive discounts of 15% and 5%. If he spends Rs 124 on transportation and sells the washing machine at a gain of 13%, then find the selling price of the machine.

एक व्यापारी 4800 रुपये के अंकित मूल्य की वाशिंग मशीन 15% और 5% की दो क्रमिक छूट पर खरीदता है । यदि वह परिवहन पर रु 124 खर्च करता है और वाशिंग मशीन को 13% के लाभ पर बेचता है, तो मशीन का विक्रय मूल्य ज्ञात कीजिए।

A) 3520

B) 4520

C) 5520

D) 2520

Correct Answer : 4520

Explanation : Selling Price = 15% and 5% of 4800
=(1 -15/100)*(1 - 5/100) *4800
=85/100 * 95/100 *4800
=3876

Actual cost price of retailer = Cost price + spend on transportation
=3876 + 124
=Rs. 4000

Selling Price of retailer= Actual cost price + Actual cost price × profit
=4000 + 4000 × 13%
=4000 + 520
=4520

Hence the selling price of the washing machine is Rs 4520
