The option second t = kqr/s is correct because t varies jointly with q and r and inversely with s
It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have:
the function t varies jointly with q and r and inversely with s.
t ∝ q×r
t ∝ 1/s
After joining:
t ∝ qr/s
After removing the proportional sign:
t = kqr/s
k is the contant of proportanility.
Thus, the option second t = kqr/s is correct because t vary jointly with q and r and inversely with s
