Answer: B) 9 Explanation:   Here in 2nd column if you add the individual digits  we get  3 + 7 + 0 =10 , 2 + 2 + 4 = 8 , 7 + 3 + 0 = 10   7   10   3  --> 7+3 =10   6   8     2  --> 6+2 =8   x   10   1  --> x+1 =10   Here we can observe that by adding 1st and 3rd column elements we get 2nd column elements  --> x = 9

Answer: B) 32 Explanation: Here the given series follows a pattern that, 22 - 0 = 4   32 - 1 = 8   42 - 2 = 14 52 - 3 = 22 62 - 4 = 32 Hence, the missing number is 32     Method 2 :: The difference between 4 and 8 is 4, the difference between 8 and 14 is 6, the difference between 14 and 22 is 8. So the next difference between 22 and the next number will be 10 since it follows (4,6,8,10 - add +2 each time) Hence, 22 + 10 = 32 is the missing number.
