Answer:
No. of boys = 216.
Step-by-step explanation:
Let the no. of boys be 4x and no. of girls be 3x. (Because if we multiply x with both 4&3
in4/3, x will cut itself and it'll cause no
effect on the original ratio)
No. of girls=162.
3x=162.
x=162/3.
x=54.
Hence, the value of x is 54.
Now, no. of boys=4x=4×54=216.(ANSWER).
