Directions: The question is based on the pie chart given below. Constituents of Sunrays received in 1 minute.

Total sun rays received in 1 minute = 3600 units

If the human body can withstand a maximum of 9720 units of IR rays, when exposed to the sun continuously, then what is the maximum time (in minutes) that any person could stand in the sun without crossing the threshold limit of IR rays?

We are given:

IR rays = 20% of total sun rays per minute

Total sun rays per minute = 3600 units

Maximum IR rays the human body can withstand = 9720 units

Step 1: Calculate IR rays received per minute

IR rays per minute=20% of 3600 = (20/100) × 3600 = 720 units/minute

Step 2: Calculate maximum time before threshold is crossed

Maximum time=9720/720 = 13.5 minutes

Hence, a person could stand in the sun for 13.5 minutes without crossing the threshold limit of IR rays.
