Ajay Vijay Ajay+Vijay+Pradeep
24 days 30 days 12 days
Total work(l.c.m 24,30,12)
24= 2^3*3
30= 2*3*5
12=2^2*3
l.c.m = 2^3*3*5 = 120
Total work = 120
Efficiecny of Ajay+Vijay+Pradeep = Tot work/Days = 120/12 = 10
Efficiency of Ajay = 120/24 = 5
Efficiency of Vijay = 120/30 = 4
Hence, Efficiency of Pradeep = 10-5-4 = 1
Given,
10 parts=== 200 Rs.
1 part== 20 Rs.
Hence Pradeep got Rs. 20 for his work
Hope it helps.
