• How many hours does Geeta work for

$\:\:$

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

$\:\:$

Let Geeta work for "x" hours

Let Shalu works for "y" hours

$\:\:$

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

$\:\:$

$\purple\longrightarrow$ $\sf y = 4x - 3$

$\:\:$

$\sf \longmapsto 9 = 4x - 3$ [ y = 9 , Given ]

$\:\:$

$\sf \longmapsto 4x = 9 + 3$

$\:\:$

$\sf \longmapsto 4x = 12$

$\:\:$

$\sf \longmapsto x = \dfrac { 12 } { 4 }$

$\:\:$

$\bf \dashrightarrow x = 3$

$\:\:$

• Hence Geeta works for 3 hours

Answer 2

Answer :

›»› 3 hours Geeta does work.

Given :

• Shalu works for three hours less than four times the number of hours Geeta works. If she works for nine hours.

To Find :

• How many hours does Geeta work for?

Solution :

Let us assume that, the work done by Geeta is x hours.

Shalu works for three hours less than four times the number of hours Geeta works.

→ Shalu works = 4x - 3

According to the given question,

She works for nine hours.

→ 4x - 3 = 9

→ 4x = 9 + 3

→ 4x = 12

→ x = 12/4

→ x = 3

Therefore,

→ Geeta work = 3 hours.

Hence, 3 hours Geeta does work.
