Neco Model Questions Vol1 2021 Biology Question 5

A high‑altitude plant experiences a 20 % reduction in atmospheric CO\(_2\) partial pressure relative to sea level. To compensate it (i) increases stomatal density by 25 %, (ii) enlarges its internal leaf surface area for gas exchange by 15 %, and (iii) develops a thicker cuticle that reduces water loss by 10 % but also lowers CO\(_2\) diffusion efficiency by 5 %. If the photosynthetic rate is directly proportional to the product of CO\(_2\) partial pressure, stomatal density and internal surface area, and is reduced proportionally by the cuticle's effect on CO\(_2\) diffusion, what is the overall multiplicative factor by which the photosynthetic rate changes compared with sea‑level conditions? Express your answer as a decimal rounded to two decimal places.
