#Percentage-1

A college has raised 75% of the amount it needs for a new building by receiving an average donation of Rs. 600 from people already solicited. People already solicited represents 60% of people, the college will ask for donations. If college is to raise exactly the amount needed for the new building, what should be the average donation (in Rs.) from remaining people to be solicited?

Solution:-
lets consider 100 people
60 people solicited
60 people pay Rs 600 each
total money=36000

 Now,
75% of total amount =36000

 25% of total amount=?

 (25/75)*36000

 =12000

#Profit&Loss-1

A shopkeeper uses false weights thereby cheats customer by giving 750 gm instead of 1 kg. He also claims that he sells rice at the cost price. In order to increase his sales he offered 125 gm of rice free with every 1 kg of rice. What is his overall percentage(approximate) profit if a customer buys 1 kg of rice and if the shopkeeper uses false weight to measure 125 gm also? Solution- Let the cost price of 1 gm of rice = Re 1 Cost Price of 750 gm = Rs. 750 Selling Price = Rs. 1000 We know that, SP = CP*(1 + Profit%) He is offering 125 gm for free but actually he is just giving 125*3/4 gms for free => SP = 1000*1 + 125*(3/4)*0 =>CP = 750 + 125*(3/4) => 1000 = (750 + 125*0.75)*(1 + Profit%) => Profit% = 18.51% Ans

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.

A building, which has 200 floors, has exactly three elevators - Elevator A, Elevator B and Elevator C. Only Elevator A stops at the ground floor (i.e., floor 0). Elevator A stops additionally at floors 5, 10, 15 and so on; Elevator B stops only at floors 4, 8, 12 and so on; Elevator C stops only at floors 6, 12, 18, 24 and so on. Further, all the floors are connected by a staircase and any floor can be reached from any other floor using this staircase.
