calories for family N
in men=  2X2400 = 4800
in women-  2X1900 = 3800
in children- 4X1800 = 7200
total =4800+3800+7200= 19400

calories for family M
in men= 4X2400 = 9600
in women= 6X1900= 11400
in children=  2X1800= 3600
total = 9600+11400+3600= 24600

proteins for family N
in men= 2X55 = 110
in women = 2X45 = 90
in children= 4X33= 132
total proteins= 110+90+132=332

porteins for family M
in men= 4X55 = 220
in women= 6X45 = 270
in children=  2X33 = 66
total = 220+270+66=556

therefore, total requirement of calories for N is 19400, for M is24600 and proteins for N is 332, for M is 556
