 \green{\underline \bold{\tt{Given :-}}}

  • Jill caught nine times three more than Jack

 \:\:

  • Half of Jill's tadpole were released

 \:\:

  • Six times as many as Jack caught swam away

 \:\:

  • At last Jill was left with three tadpoles

 \:\:

 \red{\underline \bold{\tt{To \: Find :-}}}

 \:\:

  • Number of tadpole Jack caught

 \:\:

\large{\orange{\underline{\tt{Solution :-}}}}

 \:\:

Let the number of tadpole Jack got be "x"

 \:\:

 \purple{\underline \bold{According \: to \: the \ question :}}

 \:\:

 \underline{\bold{\texttt{1st case :}}}

 \:\:

  • Jill caught nine times three more than Jack

 \:\:

⭕ Jill got = 9(x + 3)

 \:\:

 \underline{\bold{\texttt{2nd case :}}}

 \:\:

  • Half of Jill's tadpole were released

 \:\:

⭕ Jill left with =  \sf \dfrac { 9(x + 3) } { 2 }

 \:\:

 \underline{\bold{\texttt{3rd case :}}}

 \:\:

  • Six times as many as Jack caught swam away

 \:\:

⭕ At last jill got =  \sf \dfrac { 9(x + 3) } { 2 } - 6x

 \:\:

But at last Jill was left with 3 tadpoles  </strong><strong>\: </strong><strong>\: </strong><strong>\: </strong><strong>\: </strong><strong> [ Given ]

 \:\:

So,

 \:\:

 \sf \longmapsto 3 = \dfrac { 9(x + 3) } { 2 } - 6x

 \:\:

 \sf \longmapsto 3 = \dfrac { 9x + 27 } { 2 } - 6x

 \:\:

 \sf \longmapsto 3 = \dfrac { 9x + 27 - 12x } { 2 }

 \:\:

 \sf \longmapsto 6 = 9x + 27 - 12x

 \:\:

 \sf \longmapsto 6 = -3x + 27

 \:\:

 \sf \longmapsto 3x = 27 - 6

 \:\:

 \sf \longmapsto 3x = 21

 \:\:

 \sf \longmapsto x = \dfrac { 21 } { 3 }

 \:\:

 \bf \dashrightarrow x = 7

 \:\:

  • Hence Jack got 7 tadpoles
