A tree increases annually by one-fourth of its height. By how much will it increase after 2 years, if it stands today 64 cm high ?

A) 76 cm
B) 80 cm
C) 100 cm
D) 105 cm

Correct Answer:



C) 100 cm

Description for Correct answer:

Increase % = \( \Large \left(\frac{1}{4} \times 100\right) \)% = 25%.

Height after 2 years = \( \Large \left[ 64 \times \left(1 + \frac{25}{100}\right)^{2} \right] \) cm

= 100 cm.
