Math Brain Riddle:         What is the weight of each animal?                            Solution:            If two bears are 120kg, one bear is 60kg. A bear and a rabbit are 70kg If the bear is 60kg alone, then the rabbit is 10kg. Since the bear and the rabbit are 70kg, the weight remaining for the fox to complete 90kg is 20kg         

What is 1000 + 40 + 1000 + 30 + 1000 + 20 + 1000 + 10? If you can find the answer to this question, you have strong visual perception skills.                 Solution:         If you have found 2100, then you're on the right track!

Create an equation using the below numbers and mathematical symbols. Only 2 out of 10 people can solve this question           Solution:                                The answer to our question is 4+5=32          

How many squares can you see in the figure?          Solution:               There are 17 squares in total. This includes 6 small squares (1x1 unit squares), 6 medium squares (2x2 unit squares), 3 large squares (3x3 unit squares), and 2 very large squares (4x4 unit squares).

Find the value of Q in the following: Solution:  In column one (starting from right), from Q + 1 we get 3 at the units place. => Q + 1 = 3 => Q = 2 In the middle column, Q + 8 gives a number such that it has 0 at its units place. So Q = 2. This is verified by the fact that when Q (2) is added to 8 it results in 10 and hence 1 is carried forward. In the third column  4 + 3 + 1(carry) = 8.
