Apple type 1 ---- $1 per pound
Apple type 2 ---- $1.50 per pound
Orange type 1 ---- @1.25 per pound
Prange type 2 ----- @ 1.50 per pound
Required combination :
3 pounds of one variety of apples and 2 pounds of one variety of orange
Required results : We can take any variety of apple and orange to make our combination work.
Case I : $ 6.00
3*1 (apple) + 2*1.5 (orange) = 6.00 ------- Valid
II. $6.25
3*1.25 + 2*1.25
3.75 + 2.5 = 6.25 ------ Valid
III. $6.75
3*1.25 + 2*1.5 = 6.75 ----- Valid
Hence E
