Answer 1

$\large\bold\pink{AnSweR:-}$

Let Mala's Current age = x

Vani's current age = 4x

After 10 years, Mala's age = x+10

Vani's age = 4x+10

Twice Vani's age = 4 times Mala's age

$\implies$ 2(4x+10) = 4(x+10)

$\implies$ 8x+20 = 4x+40

$\implies$ 4x = 20

$\implies$ x = $\dfrac{20}{4}{/tex]= 5</p><p>[tex]\:$

Hence,

Mala's present age = 5

Vani's present age = 20
