Hi there, I need a help for the question down below

A fire policy in effect between 20.4.2017-2018.

Sum insured for the building 100.000, material 120.000, machinery 80.000.

Rate for fire in building is %0,40, in material and machinery is %0,80 and

Rate for flood in building is %0,80 and in material and machinery is %1,20.

calculate the gross premium for %20 coinsurance.

What is the gross premium?
