View Answer
Correct choice: A
Explanation:
Given Karthik can cover the distance of 200 kms resting 2 hrs per day in 22 days. Let the initial speed be '1' Hence, Time = 22(24hrs - 2) Noe new speed = 2/3 Let the number of days he take be 'D' Therefore, 22(24−2)x3 / 200=D(24−2)x2 / 250 D = 11 x 3 x 5/4 = 41.25 days. = 41 1/4 days.
