Three partners shared the profit in a business in the ratio 5 : 7 : 8. They had partnered for 14 months, 8 months and 7 months respectively. What was the ratio of their investments?
Answer: Option
Explanation:
Let their investments be Rs. x for 14 months, Rs. y for 8 months and Rs. z for 7 months respectively.
Then, 14x : 8y : 7z = 5 : 7 : 8.
| Now, | 14x | = | 5 |  98x = 40y y = |
49 | x |
| 8y | 7 | 20 |
| And, | 14x | = | 5 | 112x = 35z z = |
112 | x = | 16 | x. |
| 7z | 8 | 35 | 5 |
 x : y : z = x : |
49 | x | : | 16 | x | = 20 : 49 : 64. |
| 20 | 5 |

x:y:z= 5/14 : 7/8 : 8/7.
Let's take LCM of 14, 8 and 7 =56,
Then ,
5*4 : 7*7 : 8 : 8.
x:y:z = 20:49:64.

Let;
14x:8y:7z= 5:7:8.
As;
14x/8y=5/7,
X/y = 20/49,
Then, 8y/7z=7/8.
Y/z =49/64.
Thus x:y:z = 20:49:64.
14x:8y:7z= 5:7:8.
As;
14x/8y=5/7,
X/y = 20/49,
Then, 8y/7z=7/8.
Y/z =49/64.
Thus x:y:z = 20:49:64.

Profit = Investment * time.
P = I * T,
I = P / T,
x:y:z = 5/14 : 7/8 : 8/7,
=> 20:49:64.
P = I * T,
I = P / T,
x:y:z = 5/14 : 7/8 : 8/7,
=> 20:49:64.

Calculation of LCM is best way to find the answer. It is used for compensating purpose.

How it is possible that ratio of their investments are=ratio of their profits ?

5/14:7/8:8/7 take LCM of 14,8,7 is 56.
Multiply it 5/14 * 56 = 20.
Multiply it 5/14 * 56 = 20.

Yeah. We can do LCM.
Its just for compensating purpose only.

Hi @Swetha.
Nice.
But why 56 multiplied with those ratios?
