Rajash decided to cycle down to his grandma's house in Rampur village. The village was 42km from his house. He cycled 14.7km, then gave up and then took the bus. What percentage of the distance did he cover by bus.

65%

Step-by-step explanation:

Rajash did his way in two ways: cycling and bus. The first part he did it cycling and the second by bus. The first part on cycling covered 14.7 km of the total 42 km. Thus, the second part by bus had a distance of the remaining kilometers, this is, 42 - 14.7 km = 27.3 km.

So, we need to see what percentage of the total 42m is 27.3 km. We do this simply be dividing 27.3 over 42:

27.3 km / 42 km = 0.65 = 65 %

So, he covered 65% of the distance by bus.
