1.) The relationship among the numbers in each corner square is the same as that in the other corner squares. Find the missing number. 

(a) 10 (b) 8 (c) 6 (d)12 

Ans. : (c) 6 .

Solution: 

( 7 + 9 + 13 + 15 ) = 44 .

( 8 + 10 + 12 + 14 ) = 44 .

( 3 + 5 + 11 + 25 ) = 44 .

The sum of numbers at each corner is 44 . Hence the missing number is 

44 - (4 + 16 + 18 ) = 44 - 38 = 6 .
