Step 1: Determine the price per kilogram

Given the price of 1.5 kg apples is Rs. 60, let's find the price per kilogram.

Price per kg = Total price / Total weight in kg = 60 / 1.5

Step 2: Calculate the price per kilogram

Price per kg = 60 / 1.5 = 40 Rs/kg

Step 3: Calculate the price for 200 grams

First, convert 200 grams to kilograms: 200 grams = 0.2 kg

Price for 200 grams = Price per kg * Weight in kg = 40 * 0.2

Step 4: Calculate the price

Price for 200 grams = 40 * 0.2 = 8 Rs

= 60 km/h

Explanation

To find the fraction of work left undone, calculate the total work completed:

Day 1: 3/8

Work left undone = 1 - 5/8 = 3/8
