1.	A has 100 more mangoes than B . if A gives 60 mangoes to B then number of mangoes A has becomes 2 times that of B . How many mangoes does A has ?
Answer» Answer: 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.

Answer»

Answer:

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.
