Total sun rays received in one minute = 3600 units

Question : 38 of 150

Marks: +1, -0

The amount of Beta rays in 10 minutes of the sun rays is how many times the amount of IR rays in 3 minutes of the sun rays?

Solution:

Amount of Beta Rays in 10 minutes = 180 × 10 = 1800
Amount of IR rays in 3 minutes = 360 × 3 = 1080
∴ Required ratio =

{1800}/{1080}

= 1.66
