Given :- To serve 6 people she has to take :-
- 1 cup of refined flour .
- (1/3) cup of sugar .
- (3/10)th cup of butter .
- 2 eggs
Answer :-
→ To serve 6 people total ingredients needs = 1 + (1/3) + (3/10) + 2 = (30 + 10 + 9 + 15)/30 = (64/30) = (32/15)
→ To serve 1 people total ingredients needs = (32/15) * (1/6)
→ To serve 18 people total ingredients needs = (32/15) * (1/6) * 18 = (32/15) * 3 = (32/5) = 6(2/5) .
also,
→ To serve 3 people total ingredients needs = (32/15) * (1/6) * 3 = (32/15) * (1/2) = (16/15) = 1(1/15)
now,
→ with 2 eggs she can serve = 6 people.
so,
→ with 4 eggs she can serve = 2 * 6 = 12 people .
now,
→ with (3/10)th cup of butter she can serve = 6 people
→ with 1 cup of butter she can serve = 6 * (10/3) = 20 people .
so,
→ to serve 27 people she need butter = (27/20) = 1(7/20) cups .
