ATQ, Given 1w 12w 1x 1w 3 12w - 10 1x 1w 12w 1w3 12w-10 w 45 Number of days they take to complete the work Ishan 45 days, Bhanumati 90 days, Rajat 48 days and Govind 80 days 145 190 1x x 30 Let us assume that Nirmal takes n days to complete the work. 1w - 5 1n 1x 140 1n 130 n 120 Mohit takes 40 days and Nirmal takes 120 days to complete the work. I 8148 180 is the part of the work completed by Rajat and Govind together in 8 days. II Nirmal alone can complete the work in 120 days. III In the fractions 145, 190, 148, 180........ 145 is the maximum. So Ishan is the most efficient. All three can be answered.
