Mathematical questions are very much fun to do. I have seen many students fear Math. However if one is able to learn the basic concepts in Maths then nothing is more interesting than Mathematics. Now if we mix a little bit of Logic in Math questions to give a twist then we will have a great set of Maths brain teasers. Here are few such Math riddles to give a twist to your mind. Level of these Math brain teasers is from 5th Class onward. Any kid who is in 5th Standard or more than 10 years old should be able to solve it quickly. I will be posting the answers to these Math puzzles soon. Try to solve it without looking at answers and post your answers in the comment section of this post.

The answer to these brain teasers question of math is as below. I have hidden the answers to these riddles. To see the answer, do select the text between the numbers.

-----------------

Ans 1. a) 50H 48 min 56 sec

b) 70 m 73 cm

c) 71 kg 910g

d) 91 L 96 ml

Ans 2.

Number of 500 Rs notes= 20

Suppose number of 1000Rs notes = x

Therefore , 500x20+1000x=20000

10000 + 1000x = 20000

1000x= 20000-10000

1000x = 10000

X=10, Therefore there are 10 notes of Rs1000.

Ans 3.

The total money that Ahana has = 5000

Money spent on her dresses = 3000

Money left to buy a gift for mother= 5000-3000= 2000

Ans 4.

1,6,13,22,33,46,.. 61,78,97,118

4,9,16,25, 36, 49,64, 81

Ans 5.

87, Logic used is the sum of the place value of alphabets as shown below:

HONESTY=8+15+14+5+19+20+25=106

Ans 6.

657153324, Logic is a particular value is assigned to the alphabet in PUZZLER and FAN. We should use the same numerical value for finding out the answer. The example value of F=6, U=5, N=7, and so on..

Ans 7.

AM, DP, GS, JV, MY, PB, SE

Logic is skipping count by three of the first alphabet will give you fist alphabet of the next series and skip count by three of the second alphabet gives you the second alphabet and so on.

Example: A, B, C, D. And M N, O P.

Ans 8.

LOVE MATH.

Logic is again the value of each number is given as alphabets as 6=L, 5=O, 8=V, 3=E etc.

Ans 9.

UZZLEP. The first alphabet changed its position to last.

Ans 10.

57

+ is used to subtract, - is used to multiply and x is used to subtract again.
