Q: In a class of 30 students, 18 students study Mathematics, 15 study Science, and 10 study both subjects. How many students study only Mathematics?
Solution: To find the number of students who study only Mathematics, we use the formula: Only Mathematics = Total Mathematics - Both subjects. Thus, 18 - 10 = 8.
Steps: 5
Step 1: Identify the total number of students studying Mathematics, which is 18.
Step 2: Identify the number of students studying both Mathematics and Science, which is 10.
Step 3: To find the number of students studying only Mathematics, subtract the number of students studying both subjects from the total number of Mathematics students.
