Answer:
Step-by-step explanation:
6. Let the number be=
According to the the question,
x+(x+2)+(x+4)=87
3x+6=87
3x=81
x=
∴ First number is x=27
Second number is x+2=27+2=29
Third number is x+4=27+4=31
7. Let the number of girls = g
let the number of boys= b
Total no. of the students in the class= 35 (given)
so,
g+b=35(1)
The number of girls is two-fifth of the number of boys.
So,
From (1) and (2),
= 35
b=25
now, from (1),
g+25=35
g=35−25=10
Therefore, the no. of girls in the class is 10
