It might be nineteen because nineteen minus seven is twelve. twelve minus two is ten.
3tenths because 5tenths=50 And 2tenths=20 so if you do 50-20 you will get 30 or if u do 20+30 you will get 50 so either way is fine
Total number of people is 55
<u>Step-by-step explanation:</u>
Step 1:
Given ratio between boys and girls is 4:1. Let number of girls be x, so number of boys = 33 + x
⇒ 4x + x = x + 33 + x
⇒ 5x = 33 + 2x
⇒ 3x = 33
⇒ x = 11
Step 2:
Find total number of people.
33 + 2x = 33 + 22 = 55
