As per formulae Charge(q)=current/time(sec)=i/t
so i = q/t
q = i*t=(6*1.75)
q = 10.5
so i = q/t
q = i*t=(6*1.75)
q = 10.5

Yes Raghu is Right.

First line tells q=i/t then next line its i=q/t?

I didn't understand can any one be specific how i = q/t?

Elaborate please. How could q = current/time be equal to i = q/t sir?

Algebra:
i = q/t.
Multiply both sides by t to isolate q, so,
(t)*i = q/t* (t).
The t cancels itself out on the right side. So,
(t)*i = q.
1.75*6 = q.
10.5 = q.
i = q/t.
Multiply both sides by t to isolate q, so,
(t)*i = q/t* (t).
The t cancels itself out on the right side. So,
(t)*i = q.
1.75*6 = q.
10.5 = q.

Can anyone explain me how it's possible q=i/t equals i=q/t?

Come on guys as we know that I = Coulomb/Second.
But in this question we have to find the charge, simply take out the charge and multiply the time/current.
C = T*I = 1.75*6 = 10.5.

q = i*t.
So q = 6*1.75.
q = 10.50.
So q = 6*1.75.
q = 10.50.

Please anyone help me.
After fraction multiplication how can we decide to put dot?
