Solution

The correct option is B 30

Let’s solve this puzzle with the help of using the concepts of the number tower.

As we know the sum of two lower blocks is equal to the upper block lying on it. So 10 +20=30

Now 30+ second block = 80 hence the second block will be 50.

Now 50= 20+ third block of the first row that will be 30.
