Answer:
-1
Step-by-step explanation:
 
        
                    
             
        
        
        
Lets suppose his initial weight was 60 kilograms
A gain of 20%  would make his new eight  60 + 20*60/100
=  60 + 12
= 72 kg
he lost 25% of this:-
= 72 -   25 * 72/100 =  54 kg
This = (54/60) * 100  = 90% of his beginning weight  Answer
 
        
             
        
        
        
The formula for volume is Length x Width x Height.
So when you apply this formula to these questions the answers should be:
#7. 3x4x2 = 24
#8. 2x4x1 = 8
#9. 3x4x2 = 24
#10. 4x3x1 = 12
I hope this helps!
