Rajendra bought a mobile with 25% discount on the selling price. If the mobile cost him 4875, what is the original selling price of the mobile?


राजेंद्र ने विक्रय मूल्य पर 25% छूट के साथ एक मोबाइल खरीदा। यदि उसने मोबाइल 4875 में खरीदा है, तो मोबाइल का प्रारम्भिक विक्रय मूल्य क्या है?

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 - x/4 = 4875
3x/4 = 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%

पेप्सी और कोक दो कंपनियाँ है जो कोल्ड ड्रिंक्स बेचती है । एक समान विक्रय मूल्य के लिए पेप्सी अंकित मूल्य पर 10% और 25% की दो क्रमागत छूट दे ती है , जबकि कोक अंकित मूल्य पर 15% और 20% की दो क्रमागत छूट दे ती है । उनके अंकित मूल्यों का अनुपात ज्ञात कीजिए?

A)

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

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
