Directions : Answer the questions on the basis of the information given below. The table given below shows the discount offered on the marked price for two items  P and Q on four online websites  A, B, C and D.
The ratio of the cost price of item P is 1 : 2 : 1 : 2 for websites A, B, C and D respectively. The ratio of the selling price of item Q is 1 : 2 : 1 : 2 for websites A, B, C and D respectively.
If the marked price of Q on A is Rs.4,000 and the marked price of Q on B is 20% more than the marked price of Q on A, what is the total marked price of Q in all 4 given online websites?
The marked price of Q on B = 4000 x 1.2 = Rs.4,800 Selling price of Q on C = Selling price of Q on A = 4000 x 0.8 = Rs.3,200 Therefore, marked price of Q on C = Rs.5,000
Selling price of Q on D = 3200 x 2 = Rs.6,400 Therefore, marked price of Q on D
Rs.8,533.33
Hence, total marked price of Q in all 4 given online websites = 4000 + 4800 + 5000 + 8533.33 = Rs.22,333.33.

If the discount on P on B is Rs. 300 and the profit is 10%, what is the cost price of P on B?
Let the marked price of P on B be Rs.x.
Then, 0.15x = 300 ^ x = Rs.2,000 Therefore, selling price of P on B = 2000  300 = Rs.1,700

The ratio of the marked price of Q on A to the marked price of Q on B is 3 : 5. What is the rate of discount on Q on B?
Let the marked price of Q on A and the marked
price of Q on B be 3x and 5x respectively.
Then, selling price of Q on A = 3x x 0.8 = 2.4x Therefore, selling price of Q on B = 2.4x x 2 = 4.8x (Given selling price ratio = 1 : 2)
Hence, rate of discount of Q on B

The total cost price of P on A and on C is Rs.8,000 and the selling price of P on A is Rs. 80 more than that on C. If the profit on P on C is 10%, then what is the selling price of P on A?
Since the ratio of cost price of P on A and on C = 1 : 1 Therefore, cost price of P on A = cost price of P on 8000 C = 2 = Rs.4,000
Therefore, selling price of P on C
= 4000 x 1.1 = Rs.4,400 Hence, selling price of P on A
= 4400 + 80 = Rs.4,480.

At their wedding, Riz and Rekha received gifts amounting to a total of Rs. 1,00,000 – some of which was in cash and the rest was in the form of other articles. The cash received by them alone amounted to more than Rs. 35,000. All the cash received by them were by way of currency notes of the denominations of Rs. 2000, Rs. 500 and Rs. 200. When all the cash they received was pooled together, there were 10 notes of a certain denomination, 12 notes of a second denomination, and 16 notes of a third denomination. Riz and Rekha decided to spend an amount equal to the total value of the gifts received by them at their wedding (by way of cash and otherwise) in the ratio of 2:3 on buying a guitar and a sitar, respectively.
Which of the options below states the correct number of currency notes of each denomination received by Riz and Rekha?
The correct answer is (b) – 16 notes of Rs. 2,000; 12 notes of Rs. 500; and 10 notes of Rs. 200, which adds up to a total of Rs. 40,000. The configuration of notes in (a) would add up to Rs. 32,200. The configuration of notes in (c) would add up to Rs. 29,200. The configuration of notes in (d) would add up to Rs. 34,000. Therefore, none of the options other than (a) contains the configuration of notes that would make up for a sum of more than Rs. 35,000.
