In an educational institution, the ratio of the numbers of students in middle school and in high school, respectively, in a given year was given as 4: 3. If there were 324 students in middle school in that year in that institution, what was the number of students in high school in the same year in that institution?
- A243
- B240
- C249
- D246
Solution & Step-by-step Explanation
Let the number of students in middle school and high school be 4x and 3x respectively.
Given that the number of students in middle school is 324:
4x=324
x=
4
324
=81
Now, calculate the number of students in high school:
Number of high school students=3x=3×81=243
Given that the number of students in middle school is 324:
4x=324
x=
4
324
=81
Now, calculate the number of students in high school:
Number of high school students=3x=3×81=243
