Which number will replace the (?), if the same rule is followed in each figure?
add 17 and 15 in the 1st figure you get 32 then add 12 and 8 you get 20 now subtract 32 and 20 you will get 12 which is the middle number. Now apply the same pattern with the 2nd figure when you have applied the pattern you get 50 which is the middle number. Apply pattern in 3rd figure and you get 15
If we add left and right boxes of the 1st and2 nd figure the answers we get then add top and bottom box of the figure after we get answers or numbers of top bottom and left right minus the numbers get middle number
