You can put this solution on YOUR website!
Let N = the number of bananas he has

if he distribute them equally among the mother monkeys ,no bananas will remain.
That says N is divisible by 4.

if he distribute them equally among baby monkeys ,no banana will remain.
That says N is also divisible by 5.

if he distribute them among the mother and baby monkeys ,no banana will remain
That says N is divisible by 9.

How many bananas does Arihant have?
Since 4, 5 and 9 are "relatively prime", that is, they have no common factors 
(other than 1), you can merely multiply them together to find their least
common multiple, 4󬊉 = 180 bananas.  However he could any multiple of
180.  180 is just the LEAST number of bananas he could have.
