Problema Solution
a sum of money is to be divided among albert, brian and chrissy in the ratio 3:5:7 chrissy's share amounts to 3500
Answer provided by our tutors
Let
a = Albert's amount
b = Brian's amount
c = $3,500 Chrissy's share
a : b : 3500 = 3 : 5 : 7
a : 3500 = 3 : 7
a = (3500*3)/7
a = $1,500
b : 3,500 = 5 : 7
b = (3500*5)/7
b = $2,500
Indeed 1,500 : 2,500 : 3,500 = 15 : 25 : 35 = 3 : 5 : 7
Albert's share was $1,500.
Brian's share was $2,500.
