The currency of the country Banama is Rupas (Rp). There are exactly five denominations in which the currency is available – Rp 2, Rp 3, Rp 7, Rp 17 and Rp 19. Each of five persons, A through E, had notes of exactly one denomination with him and no two persons among the five had notes of the same denomination. On a particular day, the five persons visited a shop and each of them purchased a different product. The amounts that A through E paid the shopkeeper were Rp 102, Rp 357, Rp 399, Rp 238 and Rp 147, in that order. Further, the number of notes that each person gave the shopkeeper was distinct. However, the amount that each person paid the shopkeeper was more than the price of the product that he purchased. Therefore, the shopkeeper returned the excess amounts to each of A through E in the form of 2 notes, 4 notes, 1 note, 2 notes and 1 note respectively, but in denomination(s) different from that in which the person had paid the shopkeeper. Q1)What is the total numb

INTRODUCTION-                                  Let's go through a small story to understand all (most😛😛) the terminologies and concepts related to PROFIT-LOSS. Honey( a fashion freak) goes to a local shop to buy a T-shirt. The price of the T-shirt is Rs.500. After an altercation with the shopkeeper, Honey was able to buy that T-shirt for Rs.400. Although shopkeeper reduced the price he was able to save Rs.100 by selling that T-shirt to Honey. TERMINOLOGIES AND CONCEPTS- 1)Selling Price= Rs.400    The price at which an article is sold. 2)Cost Price = Rs.300    The actual price of the article. 3)Marked Price(Tag Price) = Rs.500    The price increased by shopkeepers to earn an extra profit is known as MARK UP(Rs.100 in this case). 4)Profit = Rs.100    Any extra money that the seller gets while selling i.e;   From Cost price to Selling Price;   Selling Price - Cost Price = Profit 5)Loss = Any extra money that seller loses while selling like selling an article that costs him Rs100

INTRODUCTION-                                   A percentage  is a number or ratio  expressed as a fraction  of 100. The sign for percent is  " %". Let's take an example. Ram scores 60 marks in a test whose maximum marks is 100 whereas Shyam scores 70 marks in a test of 140 marks.Who scored better between the two? Total maximum marks in both the cases are different so we cannot give a verdict about their performances. That's where percentage comes into the picture. Ram scored 60 out of 100 i.e; (60*100)/100 %=60% Shyam scored 70 out of 140 i.e; (70*100)/100 %=50% Now we can tell who scored better among the two i.e; RAM. From the above example, we deduce that the one use of percentage is the comparison. Let's take an example. B’s salary is 25% more than A’s salary. By what percent is A’s salary less than B’s salary? This question can be solved by 3 methods.Choose wisely😛  METHOD 1- Let A's salary be x B's salary= x+ 25%x = x+ 25x/100 =1.25 x D
