Question

A three-column table is given.

Part A C D
Part 14 28 63
Whole B 40 90


What is the value of B in the table?

Answer 1

B is equal to 20.

If we look at each of the collumns,
28 is 70% of 40.
63 is also 70% of 90.

Therefore, we can reverse this action and see that if we take 70% of 20 it is equal to 14
