Directions : The question is based on the pie chart given below.Constituents of Sunrays received in 1 minute. Total sunrays received in 1 minute = 3600 units. If presently the ozone layer in the atmosphere reflects away 60% of the sun's  rays then what would the amount of gamma rays received in one minute be, if the ozone layer were to completely disappear?   Option 1)   250 units   Option 2)   200 units   Option 3)   300 units   Option 4)   450 units   Option 5)   100 units

Hence amount of gamma rays = $\dpi{100} 100\times \frac{80}{40}=450units$
