Answers
Answer:
the left 10% studies both Maths and Science
Step-by-step explanation:
Total students = 15000
Tuition students = 15000 x 40/100 = 6000
Students studying both math and science = 6000 x 10/100 = 600
Answer:
600 Students.
Step-by-step explanation:
OK, We start with 15,000 students.
40% of them had tuition, so the actual number of them that had tuition is :
15,000*
0.40 = 6,000
Now we want to find a number of students that studied math and Science.
50% only studied Math.
30% only studied Science.
10% studied other subjects.
So,
50%+30%+10% did not studied both math and science.
90% is the percentage that did not study Mathematics as well as Science, then the order 10% did.
Then, out of the 6,000 Students that had tuition, 10% Studied Math and Science,
The total number is :
6,000*0.10 = 600.
