Question 1169167:  1.Three business partners A, B and C share the profits as follows  
the ratio of A's share to B's share is 6:5 and the ratio of B's share to C's share is 3:4 Determine:  
1.1 A's share:B's share:C's share 
1.2 The total profit if A gets $5000 less than C

you are given:
 
 
a represents a's share of the profits 
b represents b's share of the profits. 
c represents c's share of the profits.
 
 
a/b = 6/5 
b/c = 3/4
 
 
 
from a/b = 6/5, solve for a to get a = 6/5 * b
 
 
from b/c = 3/4, solve for c to get c = 4/3 * b
 
 
you know that a + b + c = p, where p represents total profit.
 
 
replace a and c with their equivalent values in b to get: 
6/5 * b + b + 4/3 * b = p 
multiply both sides of this equation 15 to get: 
18 * b + 15 * b + 20 * b = 15 * p 
add them up to get: 
53 * b = 15 * p 
divide both sides of this equation by 15 to get: 
b = 15/53 * p
 
 
since a = 6/5 * b, then: 
a = 6/5 * 15/53 * p 
simplify to get: 
a = 18/53 * p
 
 
since c = 4/3 * b, then: 
c = 4/3 * 15/53 * p 
simplify to get: 
c = 20/53 * p
 
 
add them up to get:
 
 
p = a + b + c = 18/53 * p + 15/53 * p + 20/53 * p
 
 
your answers for part 1.1 are:
 
 
a's share is equal to 18/53 * total profit. 
b's share is equal to 15/53 * total profit. 
c's share is equal to 20/53 * total profit.
 
 
if a gets 5000 less than c, you get: 
a = c - 5000 
since a = 18/53 * p and c = 20/53 * p, then you get: 
18/53 * p = 20/53 * p - 5000 
subtract 18/53 * p from both sides of this equation and add 5000 to both sides of this equation to get: 
5000 = 2/53 * p 
solve for p to get: 
p = 5000 * 53/2 = 132500
 
 
a's share is 18/53 * 132500 = 45000 
b's share is 15/53 * 132500 = 37500 
c's share is 20/53 * 132500 = 50000
 
 
ratio of a's share to b's share is 45000/37500 = 6/5 
ratio of b's share to c's share is 37500 / 50000 = 3/4
 
 
requirements of the problem are satisfied. 
solution looks good.
 
 
solution is:
 
 
a's share is 18/53 * 132500 = 45000 
b's share is 15/53 * 132500 = 37500 
c's share is 20/53 * 132500 = 50000
