Answer:
There are 2 girls & 10 boys, this makes it that there are 8 more boys, while still in the 1:5 ratio given.
Total class strength is of 12; 2 + 10 + 12 (as far as maths is still the same).

Answer:
the total strength of the class is 12
Step-by-step explanation:
Given,
the ratio of boys: girls = 1:5
and the no.of girls is 8 more than the no. of boys
Let the no.of girls be x and no.of boys be y
y+8=x
y\x = 1\5
by cross multiplying the above equation
y= x\5 ( substituting this in the eqn y+8=x)
x\5 + 8= x ( multiplying 5 to the whole eqn)
x + 40= 5x
x-5x = -40
4x= 40
x= 10
therefore girls are 10 in no
and boys are 2
therefore total strength of the class is 12
