15
Step-by-step explanation:
The total number of teachers in the school is 100.
The number who teach Science is 60

Step-by-step explanation:
The equation of line passing through the two points is
When substituted,the equation becomes
which when simplified is
The line clearly passes through origin.
The distance between two points is
Distance between origin and is
.
Distance between origin and is
Scale factor is
So,scale factor is
which when simplified becomes 3.
