the ratio of the number of boys to the number of girls in a school of 720 students is 3:5 if 18 new girls are admitted in the school find how many new boys may be admitted so that the ratio of the number of boys to the number of girls may change to 2:3

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
