The height of a plant increases at the rate of 2% per annum. If its present height is 1.2 m, then what will be the height of the plant after three years?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 1.273 m.
Given that
The current height of the plant is 1.2 m
The height is increased by 2% every year
After 3 years
The height = 1.2 × (102/100) × (102/100) × (102/100)
= 1.273 m (approx.)
