Answer:
215
Step-by-step explanation:
subtract 30 from 225
V=(LxWxH)/3 so, V= (9x12x15)/3 = 1,620/3 = 540m^3. From here you multiply 540m^3 by 3,000kg/m^3 and get 1,620,000kg. Then you divide 1,620,000kg by 2,000kg/metric tonne and get 810 metric tonnes.
Let the two numbers be x and y
As given, the difference of two numbers is 3, so
or
....(1)
And their sum is 25, so
.....(2)
Putting x=3+y in equation (2)



As, x+y=25


So the two numbers are = 14 and 11
