Problema Solution
share a property worth 775000 if a :b 3: 2 b :c 5: 4 and c: d 3: 7 find the share of b
Answer provided by our tutors
a + b + c + d = 775000
a/b = 3/2 => a = 3b/2
b/c = 5/4 => c = 4b/5
c/d = 3/7 => d = 7c/3 = 7*(4b/5)/3 = 28b/15
by plugin the values of a, c, d in the first equation a + b + c + d = 775000 we get
3b/2 + b + 4b/5 +28b/15 = 775000
by solving it for b we find
b = 150,000
