Explanation
Given:
Height of pole is 75 inches Calculation: Caterpillar crawls 5 inches in a day and slide down 4 inches in night Total distance cover by caterpillar day and night = 5 - 4 ⇒ 1 inches Total distance to cover by caterpillar in 70 days = 70 inches Remaining = 75 – 70 ⇒ 5 inches Caterpillar takes 1 day to cover 5 inches Total days required to reach the top = 70 + 1 ⇒ 71 days ∴ It will reach at the end of 71 days.
