Hello everyone! I’m back and today we continue to find the solution for the next exercise. It is “Table 1 shows the distribution of scores among students for the four subjects (figures in %) and Table 2 shows the distribution”. Let’s do the exercises together!

Table 1 shows the distribution of scores among students for the four subjects (figures in %)

and Table 2 shows the distribution of subjects for students having scores greater than 60 and less than or equal to 80 (figures in %).

Which of the following is closest to the ratio of the total number of students who scored greater than 80 and less than or equal to 100 and the total number of students who scored greater than 40 and less than or equal to 60?

- 2:5
- 3:11
- 1:2
- 3:5

## Answer

Number of students with scores greater than 80 or less than/equal to 100 = 6 +10 + 10 + 16 = 42

The total number of students who scored higher than 40 and lower than/equal to 60 is 48 + 40 + 40 +36 = 164

This ratio is 42/164 = 21/82, which is almost equal to 3/11.

Therefore, the answer is (2).

## Relevant knowledge

When comparing two numbers, one can use the concept of a percentage to say what percentage of one number is equal to the other. For example 20 equals 20% of 100,…

It is summed up that there are 3 basic problems when it comes to percentages and this problem can be extended to practice.

1. Find the percentage of 2 numbers

To find the ratio of number A to number B, divide A by number B and multiply by 100.

2. Find the percentage of a number

To find the percentage of a number, divide the number by 100 and multiply by the percentage, or multiply the number by the percentage and then divide by 100.

3. Find a number when the percentage of that number is known

To find a number when you know the percentage of that number, divide that value by the percentage and then multiply it by 100 or take that value by 100 and then divide it by the percentage.

## Conclusion

Above we have given you the answer to the lesson “** Table 1 shows the distribution of scores among students for the four subjects (figures in %) and Table 2 shows the distribution**“. Hope you get good results in your studies. Thanks for reading!
