Right it is not declared but the term curve seems something to be the given figure 1000 is the radius.

But it is not declared that 1000 m is the radius of the curve.

Actually, in the problem, it shows that horizontal curve is 1000m but in explanation, they take 1000m as a radius why don't they take it as length of the curve?

e = V^2/225R.
= 75 * 75/(225*1000).
= 1/40 (or).
= 1 in 40.
= 75 * 75/(225*1000).
= 1/40 (or).
= 1 in 40.

Why 75% is taken for design speed?

F is not gives that doesn't mean we will not use 127 Maximum times we use 127 for already designed roads.

1 in 40 is the right answer.
V^2/125r ( f is not given).
V^2/125r ( f is not given).

1/40 is the right answer.

Why used 75% in que not mention mixed traffic?

Here,
e = v2/gr when v is in m/s.
e = v2 /127r when v is in kmph.
e = v2/gr when v is in m/s.
e = v2 /127r when v is in kmph.
