The table shows the number of saplings planted by four schools in three years.
What is the average number of saplings planted per year by school Deodar?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 151
The average per year = total of the row ÷ number of years.
Deodar: 120 in 2019, 176 in 2020, 157 in 2021
Total \(=120+176+157=453\)
Average \(\displaystyle =\frac{453}{3}=151\)
School Deodar planted on average 151 saplings per year.
