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 with explanation:

 Number of Apples Possessed by Davis = 10

 Number of Apple ate by Gus

   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

any options?

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
