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

In atmosphere with ozone, gamma rays = 5% of 3600 = 180

60% of the rays = 180 units

If ozone layer were to disappear we would receive 100 % of rays

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