If you take positive and negative half cycle both then devide by 20.

Why? (Vrms =0.5).

Vmax = 60 then Vrms = 0.5,
Multiply by 60 = 30,
The answer due to +ve half cycle.
Multiply by 60 = 30,
The answer due to +ve half cycle.

I think it should be simply,
Vmax / 1.414. Vmax = 60v.
Vmax / 1.414. Vmax = 60v.

@Rathi.
Because there are 10 positive cycles on the numerator.
Because there are 10 positive cycles on the numerator.
