the number of girls and boys are in ratio of 10:7. the number of boys is 6 more than number of girls what is the total strength of the class
Answers
Answer:
No. of boys = 20
No. of girls = 14
Step-by-step explanation:
Let us consider,
No. of boys in class = 10x and
No. of girls in class = 7x
The number of boys is 6 more than that of
girls............. (given)
Therefore,
10x+6 = 7x
10x - 7x = 6
3x = 6
x = 6 /3
x = 2
Therefore,
No. of boys = 10x = 10 × 2 = 20
No. of girls = 7x = 7 × 2 = 14.
Step-by-step explanation:
★Correct Question:-
the number of boys and girls are in ratio of 10:7. the number of boys is 6 more than number of girls what is the total strength of the class.
★Solution
If it's been given that boys are more than the girls, it means boys have a greater ratio.
Let the ratio of boy and girls be 10x and 7x respectively.
We've been given that number of boys is 6 more than the number of girls.
So we can conclude that,
The difference between the ratio of boys to girls will give 6 as it's mentioned that number of boys is 6 more than number of girls.
10x - 7 x = 6
3x = 6
x = 2.
Number of boys = 10x = 10(2) = 20
Number of girls. = 7x = 7(2) = 14.
Now, we've to find the total number is of students.
Total number of students = Number of boys + Number of girls.
Total number of students = 20+14
Total number of students = 34.
Therefore, the total strength of the class is 34.
