Based on the concept of percentages in maths I have included few questions that will help to understand concept of time, distance and speed better. The percentage concept is quite easy. X % mean X/100. Otherwise to solve questions you need simple logic
The quiz goes in here.

If the price of onion increases by 30 % and sweety plans to spend only an additional 10% on onion, by how much % will she reduce the quantity of onion purchased?
Question 1 Explanation:
If the price of onion is Rs X/kg, then after increase it will 1.3X/kg
Suppose Sweety intially used to buy Y kgs then her spend beore price increase is Rs XY. But after price increase it is 1.3XY.
If she intends to increase the spend by only 10% then suppose she buy quantity Z. i.e she wants to spend only 10 % more of XY = 1.1 XY
1.2 XY = 1.3XZ
or Z = 11/13 = 85 % (use approximation) or Sweety will have to buy 15 % less onions to keep the expense rise to 10 %
There are 1000 chickens in a poultry farm in year May 2010. Due to normal growth the number of chicken grows by x % by next month in June 2010. Due to a disease spread in poultry many of chikens die in July 2010 at the Y %. However owner finds the chicken number reamin sames to 1000. What Can we say growth of X % in June 2010 as compared to Y% in July 2010
X = Y
X > Y
X < Y
Question 2 Explanation:
ust put in some value and check let say X = 10 and Y = 11
June 2010 No. of chickens are 1100, Now if July after population decrease n. of chicken is by say Y % then
1000 = 1100 - 1100 x Y/100
10/11 = 1 - Y/100
Y = 100/11
hence X > Y
If in a college election contested by only two Ram and Shyam, Ram secured 20 % of the total votes more than Shyam. If Shyam got 400 votes, by how many votes did it lose the election?
Question 3 Explanation:
Let us assume Ram has secured X % Votes, then % Votes secured by Shyam is ( X - 15) % . Since there are only 2 parties addition of these two should amount to 100 %
X + X - 20= 100
2X = 120 or X = 60 %
Ram got 60 % votes and Shyam got 40 % Vote
If the total votes is V then Shaym 40 % is equal to 400
or V = 1000 , Ram Votes is 600 and Shaym is 400
Shaym lost by 200 votes
Student securing 20% marks fails by 15 marks but another who gets 45% marks gets 10% more than the passing marks. What is the maximum marks?
Question 4 Explanation:
Passing cut-off mark is at 30 % ( 42 % - 12 %)
Suppose max. mark is X then as per statement
Passing mark (35 %) - 20% of max. marks fails by 10 marks
15 % of X = 15
So Max marks is 100
Strawberry Jams are made by cooking over stove and reducing water. If the strawberry contain 40 % of water then how many strawberries need to be extracted so that 1 Kg Jam can be made with only 20 % of water content
Question 5 Explanation:

Since the pulp remain same
40 % of Strawberry = (100 - 20) % x Jam weight
Strawberry = 80 / 40 = 2 Kgs of Strawberry are required
