Question
Sonu and Raj have to collect different kinds of leaves for science project. They go to a park where Sonu collects 12 leaves and Raj collects x leaves. After some time Sonu loses 3 leaves and Raj collects 2x leaves. Write an algebraic expression to find the total number of leaves collected by both of them.
Solution
According to the question,
Sonu collected leaves = 12 – 3 = 9
Raj collected leaves = x + 2x = 3x
∴ Total leaves collected = 9 + 3x
Hence, the required expression is 9 + 3x.
