## Did you try each several times?

Here are the answers to Brain Practice, May 2019

#### How many socks?

There are 22 blue and 35 black socks in a drawer. How many socks to you need to take out of the drawer to find a matching pair?

#### Crack the Code

It’s 042

1-from the first two hints you understand that 6 is definitely not in the key
2-from the third one you understand 2 and 0 is in the key but not in that order (as it cannot be 6)
3-when you look at the fourth one it is clear 8 is not in the key so in the first hint only the 2 can be the key and it is in the right place. (Now that you know 2’s position, you can look at the third hint and understand that 0 is in the first as the last place is taken and middle is incorrect  – so from this point on you actually don’t need the fourth and fifth hints.
4- fourth hint gives you 7-3-8 are not in the key so from the fifth hint you can understand 0 is in the wrong place and looking back at the third hint 0 should be first and 2 should be last leopard = 5

zebra = 8

giraffe = 3

Result = 16

#### Find the Pattern

Solution:- Find the Pattern,

Every time, The Number  in L.H.S (Left Hand Side)  is Put in the First place  in R.H.S (Right Hand Side)

1 = 5
1 = 52 = 25
2 = 253 = 325
3 = 3254 = 4325
4 = 4325
So,   5 =54325
