Class 10th – Mathematics (Sindh Textbook Board)
Unit 18: Variations
Exercise 18.1 (Questions 3 to 7)

In Exercise 18.1 (Q3 to 7) of Unit 18: Variations, students learn to solve problems involving direct, inverse, and joint variations. These questions help in understanding how one quantity changes with respect to another.

Q3 & Q4 focus on identifying and proving direct and inverse variations using given sets of values.

Q5 involves solving numerical problems where two quantities vary directly or inversely, and finding unknown values.

Q6 introduces the concept of joint variation, where one variable depends on two or more others simultaneously.

Q7 provides real-life applications of variation, helping students understand how these mathematical relationships apply to practical situations.


This part of the exercise strengthens problem-solving skills and builds a clear understanding of the relationships between varying quantities.
