Answer:
Step-by-step explanation:
let the total number of students be x
According to question
2/3of x are boys
And 17 are girls
Hence,
2x/3+17=x
=>(2x+51)/3=x
=>2x+51=3x
=>2x-3x=-51
=>-x =51
Therefore x =51
So
a) =2x/3
=2*51/3
=102/3
=34
b) total students
=number of boys +number of girls
=34+17
=x (the total number of students)
=51

Answer:
Hello
Let total strength be x.
No of boys is 2/3 of x
no of girls = 17
then 2x/3=x
(2x+51)=3x
51=3x-2x
x=51
no of boys =(2/3)×51=34
so, the total stength is 51 and no of boys is 34.
