Answer 1

Step-by-step explanation:

1) question is incomplete

Fill the commission by yourself

I am taking the the commission as x%

Value of the land =(75688/x)*100

2) weight of the ore = (63/18)*100

= 350 kg

3)present value=3,45,000

Value after 1 year = (3,45,000/100)*(100-20)

=3450*80

= 2,76,000

Value after 2 years= (2,76,000/100)*(100-20)

= 2760*80

=2,20,800
