Answer 1

Hello friend

Weight of the wedding cake is 8kg

2/5 of the cakes weight is flour

Then weight of flour is (2/5)*8=16/5=3.2kg

5/16 of the cake's weight is sugar

Then weight of the sugar is (5/16)*8=2.5kg

1/4 of cakes weight is cream

Then weight of the cream is (1/4)*8=2kg

Weight of the nuts is total weight of the cake-(weight of flour+weight of sugar+weight of cream)

=8-(3.2+2.5+2)

=8-7.7

=0.3

Weight of nuts is 0.3kg or 300gms
