Answer of these brain teasers question of math are as below. I have hidden the answers of 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.

Money spent for her dresses = 3000
Money left to buy gift for mother= 5000-3000= 2000

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

Ans 5. 
87,  Logic used is sum of the  place value of alphabets as shown below:

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

Ans 7. 
AM ,  DP,  GS,   JV, MY, PB, SE
Logic is skip count by three of first alphabet will give you fist alphabet of next series and skip count by three of second alphabet gives you second alphabet and so on.
 Example : A,   B,    C  ,   D. And M      N,     O    P.

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

Ans 9. 
UZZLEP. First alphabet changed its position to last.

Ans 10.
