Correct Answer - Option 1 : 25 km

According to the given question

Given:

A covers 25% of distance on foot and 30% of remaining distance by car and remaining 45 km by bicycle

Concept used:

Unitary method

Calculation:

Let the total distance be D

∴ D = (D/4 + 3D/10 + 45)

⇒ 9D/20 = 45 km

⇒ D = 100 km

Now, A covers 25% of distance by foot

∴ Distance cover by foot = 25% of 100 km = 25 km

Hence, option (1) is correct
