Let X be number of mangoes
Number of apples = x+17
(x)(3.20)+(x+17)(0.40)=111.20
3.20x+0.4x+6.80=111.20
3.20x+0.4x=104.40
3.6x=104.40
x=104.4/3.6
x=29
Number of mangoes =29
Number of apples =29+17=46
Number of apples = x+17
(x)(3.20)+(x+17)(0.40)=111.20
3.20x+0.4x+6.80=111.20
3.20x+0.4x=104.40
3.6x=104.40
x=104.4/3.6
x=29
Number of mangoes =29
Number of apples =29+17=46
