Amy is 9 years older than her younger sister. if her younger sister is now 1 year old, how many years later will Amy be 4 times
Sholpan [36]
<h3><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u>:</u><u>-</u></h3>

  • Age of Amy's younger sister=1year

☆Amy is 9 years older than her younger sister.

\\ \sf\longmapsto Age\:of\:Amy=1+9=10years

Let after x years Amy will be 4times old as her sister.

ATQ

\\ \sf\longmapsto \dfrac{1+x}{9+x}=\dfrac{1}{4}

  • Using cross multiplication

\\ \sf\longmapsto 4(1+x)=1(9+x)

\\ \sf\longmapsto 4+4x=9+x

\\ \sf\longmapsto 4x-x=9-4

\\ \sf\longmapsto 3x=5

\\ \sf\longmapsto x=\dfrac{5}{3}

\\ \sf\longmapsto x=1.6

\\ \sf\longmapsto x=2(approx)
