Answer:
62 mangoes
Step-by-step explanation:
Let the number of mangoes A has, be x
and the number of mangoes B has , be y .
∴30+x=2(y−30)⟶(i) ,as A says
and , 10+y=3(x−10)⟶(ii) ,as B says
On simplification ,
x−2y+90=0⟶(iii)
−6x+2y+80=0⟶(iv)
On adding (iii) and (iv),
−5x+170=0
⇒x=34 mangoes.
putting x in (i),
34−2y+90=0
2y=124
y=62 mangoes.
