Question

Davis has ten apples. Gus is hungry and eats a fifth of them, but Davis buys twice the amount gus ate the next day. How many apples is Davis left with after the purchase?

Answer 1

whole=10
1/5 of 10= 2, Gus ate 2
2*2= 4 apples.
Davis has 8 apples, then he buys 4
He has 12 apples

Answer 2

Answer with explanation:

 Number of Apples Possessed by Davis = 10

 Number of Apple ate by Gus

                 $=\frac{1}{5}\times 10\\\\=2$

   Number of Apple bought by Davis next day

           =Twice the Amount ate by Gus

           = 2 × 2

           =4      

So, total number of Apples left with David

           =10 -(  Number of Apple ate by Gus)+( Number of Apple Bought by Davis next day )

                  =10 - 2 +4

                   =8+4

                  = 12 Apples
