Question

1+5=18
2+7=27
3+9=36
5+10=45
4+20=?​

Answer 1

Answer:

answer is 72

Step-by-step explanation:

In each of the equations, each of the values to the left of the equal sign is tripled to make the equation correct. Thus, 1+5 becomes 3+15=18.

Similarly, 2+7 becomes 6+21=27;

3+9 becomes 9+27=36;

5+10 becomes 15+30=45; and

4+20 becomes 12+60=72.
