A , B and C started a business by investing a business in a way that A:B = 1:2 and B:C = 3:4 ,
what will be the share of A in a company profit of Rs 68000:
:
A + B + C = 68000
A = 2B
and
4C = 3B
C = 3%2F4B
or
C = .75B
:
Replace A & C in the first equation
2B + B + .75B = 68000
3.75B = 68000
B = 68000/3.75
B = $18,133.33 is B's share
:
C = .75(18133.33)
C = $13,600 is C's share
:
A = 2(18133.33)
A = $36,366.67 is A's share

You can check this for yourself, add up the 3 shares

Play with the given ratios so that the number for B in both ratios is the same. It's like finding a common denominator when adding or subtracting fractions.

In the first ratio, the number for B is 2; the second, the number for B is 3. So multiply both numbers in the first ratio by 3 and both numbers in the second ratio by 2; that will make 6 the number for B in both ratios. Then you can combine the two ratios into a single ratio.

1:2 --> 3:6
3:4 --> 6:8

So
A:B:C = 3:6:8

Now with all three numbers expressed in a single ratio, we can let the amounts for A, B, and C be represented by 3x, 6x, and 8x. Then, since the total is 68000,
3x%2B6x%2B8x+=+68000
17x+=+68000
x+=+4000

So the amounts the three business owners should get are
A: 3x = 12000
B: 6x = 24000
C: 8x = 32000



Note: the answers from the first tutor are wrong. While his method was fine, he accidentally wrote 4C=3B, where it should have been 3C=4B...
