Can you determine the missing number in the box? The same rule of logic applies to all three boxes?

The missing number is 24. The rule is to double the first number in each rectangle and place that number in the next box below it.

24 in each box 2nd number=1st*2 3rd number=2nd*2 4th number=3rd*2 like this

24, 12/6=2*24=48

Look at the hints given in the box and guess the logic behind the answers and then find the missing number.

By deducing the logic used in the table below, can you find the missing number?

Find the missing number, if same rule is followed row-wise or column-wise.

If the figures having some characters given below follow the same rule, then find the missing number from the options?
