Answer 2

Answer:

14 Lemon , 1 Orange  , 5 Apples

16 Lemons , 4 Oranges , 0 Apples

Explanation:

O + A  + L  = 20

3O + 2A  + 0.5L  = 20

Maximum O Can be  6

if O = 6

then

A + L = 14

2A + 0.5L = 2

=> 3A = -10

Hence not possible

if O = 5

then

A + L = 15

2A + 0.5L = 5

=> 3A = - 5

if O = 4

then

A + L = 16

2A + 0.5L = 8

=> 3A = 0

=> A = 0   ,  L  = 16   ,  O = 4

if O = 3

then

A + L = 17

2A + 0.5L = 11

=> 3A = 5  hence A is not integer

if O = 2

then

A + L = 18

2A + 0.5L = 14

=> 3A =  10  hence A is not integer

if O = 1

then

A + L = 19

2A + 0.5L = 17

=> 3A =  15

=> A = 5   ,  L  = 14  ,  O = 1
