A vertical summit curve on a freight corridor is formed at the intersection of two gradients, +3.0% and −5.0%.

Assume the following:
- Only large-sized trucks are allowed on this corridor
- Design speed = 80 kmph
- Eye height of truck drivers above the road surface = 2.30 m
- Height of object above the road surface for which trucks need to stop = 0.35 m
- Total reaction time of the truck drivers = 2.0 s
- Coefficient of longitudinal friction of the road = 0.36
- Stopping sight distance gets compensated on the gradient

The design length of the summit curve (in meters) to accommodate the stopping sight distance is _____ (rounded off to 2 decimal places).

If '→' denotes increasing order of intensity, then the meaning of the words [drizzle → rain → downpour] is analogous to [ ______ → quarrel → feud].

Which one of the given options is appropriate to fill the blank?

Statements:

1. All heroes are winners.

2. All winners are lucky people.

Inferences:

I. All lucky people are heroes.

II. Some lucky people are heroes.

III. Some winners are heroes.

Which of the above inferences can be logically deduced from statements 1 and 2?

A student was supposed to multiply a positive real number $p$ with another positive real number $q$. Instead, the student divided $p$ by $q$. If the percentage error in the student’s answer is 80%, the value of $q$ is
