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?

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?

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%

Pepsi and Coke, there are two companies, selling the packs of cold­drinks. For the same selling price Pepsi gives two successive discounts of 10% and 25% on marked price, while Coke sells it by giving two successive discounts of 15% and 20% on marked price. What is the ratio of their marked price?

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 ?

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 ?

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.

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
