Question

What number should replace the question mark in the grid?

Answer 1

12 (twelve) row adsation should be 26 (0 + 4 + 1+ 9) =26

Answer 2

Sum of all nos
In first row=31.
In second row=26 (31-5)
In third row=23 (26-3)
In fourth row=21 (23-2)
He re the no which is subtracting from the sum is decreading by 2,1,0..so next we have to subtract 2-0=2 from the sum.
Fifth row shold be 21-2=19
So the ans should be 5.

Answer 3

6

96475 - 62918 = 33557
62918 - 33557 = 29361
33557 - 29361 = 04196

Subtraction. The answer is 6
