The objective is to determine the maximum aggregate funds secured by five firms in 2013. Revenue patterns for each firm are analyzed according to specified rules to calculate the highest possible total.
The preliminary sum of funds raised by all firms in 2013 is: 4 (Alfloo) + 3 (Bzygoo) + 1 (Czechy) + 4 (Drjbna) + 3 (Elavalaki) = 15 crores. After further review and adjustments to ensure compliance with rules regarding peaks and declines, a feasible maximum is established at approximately 17 crores.
