Maths puzzle questions are often asked in a number of competitive exams. Most of the questions are based on arithmetic or number puzzles. Some of the riddles test your basics of clocks, profit-loss, probability, time, speed and distance. Here is a compilation of medium level maths puzzles with answers. You will be able to solve the concept based questions in form of algebra puzzles. Each article consists of 10 questions.

- 185
- 156
- 625

Clearly, ( 52-32 )= 16, ( 122-82 )= 80, ( 342-272 )= 427,So missing number is: ( 212-162 )= 185,. So answer is (b) option.

Marked Price=100

After discount price = 75

Profit is 25% so Cost price = 60

If they give 10% discount, then Price = 90

Profit % = (30/60) x 100 = 50%

4 legged chairs = 4 legged tables = number of workers.

3 legged stools = 4 legged almirahs

No. of stools = 1 + no. of workers

Total no. of legs = 585, Let the total number of workers= x.

2x + x × 4 + (x+1) 3 + (x+1) 4 = 585....x = 34.

Thus number of workers are 34.

So answer is 6×10 = 60.

After midnight at 9.00 A.M. Movement = 30×8 = 240°. In 20 minutes movement = 20x30/60 = 10° Total= 240° + 10° = 250°.

Imagine two people walking along the path toward each other at the same time (one from the top of the hill, the other one from the bottom). Obviously, they must meet somewhere along the way.

Smallest of the greatest will be greater than greatest of the smallest. Consider number X who is at the intersection of the column with the greatest of the smallest (G), and the row with the smallest of the greatest (S). Clearly, S ≥ X ≥ G (the equality will happen if the smallest of the greatest is the same number as the greatest of the smallest). Therefore, S > T.

Following is the list of the numbers that can be constructed each month.

January: 2 to 32 (From 1st January - 31st January)

February: 3 to 30 (From 1st February - 28th February)

Total 42 numbers are possible, every number between 2 and 43 inclusive

- 23; 2:1
- 17; 19:17
- Either; 18:1
- Either; 35:1

Since each of the spin is an independent event, thus the outcome of the 13th spin will not depend on the outcome of the previous spins. Hence, the odds of winning on the number that Anurag bets on, is 35 : 1 in each case.

Mr. Jain crosses exactly seven trains on the route - 3 trains which had already started before the start of Mr. Jain while 4 trains will be those which started after the start of Mr. Jain.
