Answer:24
Step-by-step explanation:
Since the numbers in the middle are 21 and 27, you add both and divide by 2 to get the number in the middle of those 2.
A 50% increase is just taking the original amount and adding half of that towards the amount.
Example : 50% of 100 is 50 so a 50% increase to 100 would be 150
a formula for this would be X + (1/2×X) = Y
in your case we're working backwards with the known being 60
We can just plug in reasonable values for X until we get 60
50% of 40 is 20
40 + 20 = 60
so the original amount was 40
