Dear Ramesh Garu,
Your tricks and logics of mathematics are amazing. I have a doubt on this. You have explained how to find prime number for bigger numbers by finding square number. My kid is of Grade 5. Children are unable to understand square number at this stage. Can you explain the any other alternative trick to find prime numbers for bigger numbers?

Time work one problem clear cheyandi

Bc80days
Ac120 days chestaru one work
B okkade enni days lo cheyagaladu

[@harishkatta1]

Only B Can complete in 96 days

[@magapuanilkumar4167]

Total work = LCM ( 60, 80, 120) = 240 units
Efficiency of ( A+B) = 240/60 = 4 units/day
Efficiency of ( B+C) = 240/80 = 3 units/day
Efficiency of ( C+A) = 240/120 = 2 units/day
Total efficiency 2(A+B+C) = 4+3+2
Therefore A+B+C = 9/2 = 4.5 units/day
B Efficiency = (A+B+C) - (A+C) = 4.5 - 2 = 2.5 units/day
No. of days = Total work / efficiency
B's days = 240/2.5 = 96 days
