The 2nd one goes makes three portion of the remaining but there was one extra left so he took 1 portion and the extra one also! Then the last one goes and took all remaining mangoes! When they saw hoW many each had they were surprised bECAUSE all had equal mangoes! SO HOW MANY MANGOES WERE LYING ON GROUND INITIALLY!?
