Answer:

240 teachers

Step-by-step explanation:

Let u be 1 unit.

1u+12u=260

13u=260

u=260÷13

=20

No. of teachers=12u=20×12

=240

Let teacher be x

  • Student=12x

[tex]\\ \sf\longmapsto x+12x=260[/tex]

[tex]\\ \sf\longmapsto 13x=260[/tex]

[tex]\\ \sf\longmapsto x=\dfrac{260}{13}[/tex]

[tex]\\ \sf\longmapsto x=20[/tex]
