 - A : B : C = 27000 : 72000 : 81000 = 3: 8 : 9. so, C’s share : Total Profit = 9 : 20.
Let the total profit be Rs. x. Then, 9/20 = 36000/x or x
= 36000 x 20 / 9 = 80000.
 - Suppose Y invested Rs. y.
Then, 40000/y = 2/3 or y
= [40000 x 3 / 2] = 60000.
 - Let the initial investments of A and B be 3a amd 5a.
A : B : C = (3a x 12) : (5a x 12) : (5a x 6) = 36 : 60 : 30 = 6 : 10 : 5.
 - A : B : C = 10 x 7 : 12 x 5 : 15 x 3
= 70 : 60 : 45
= 14 : 12 : 9.
∴ C’s rent = Rs. [175 x 9/35] = Rs. 45.
- Clearly, Manish invested his capital for 12 months, Vibhor for 9 months and Vivek for 3 months.
So, ratio of their capitals = (45000 x 12) : (60000 x 9) : (90000 x 3)
= 540000 : 540000 : 270000 = 2:2:1.
∴ Manish’s share = Rs. [16500 x 2/5] = Rs. 6600;
Vibhors share = Rs. [16500 x 2/5] = Rs. 6600;
Vivek’s share = Rs. [16500 x 1/5] = Rs. 3300.
To find the share of Vivek in the profit, we need to calculate the ratio of the investment of each person and the time period for which they invested in the business. The ratio of profit sharing for Manish, Vibhor, and Vivek is calculated as follows:
Manish's investment = Rs. 45,000 (He invested for the entire year)
Vibhor's investment = Rs. 60,000 (He invested for 9 months)
Vivek's investment = Rs. 90,000 (He invested for 6 months)
To find the ratio of profit sharing, we can multiply the investment by the time period for each person:
Manish's ratio = 45,000 × 12 = 5,40,000
Vibhor's ratio = 60,000 × 9 = 5,40,000
Vivek's ratio = 90,000 × 6 = 5,40,000
The total ratio of profit sharing is:
Manish + Vibhor + Vivek = 5,40,000 + 5,40,000 + 5,40,000 = 16,20,000
The share of Vivek can be calculated by dividing his ratio by the total ratio and then multiplying the result by the total profit:
Vivek's share = (Vivek's ratio / Total ratio) × Total profit
Vivek's share = (5,40,000 / 16,20,000) × 16,500
Vivek's share = 5,500
Therefore, the share of Vivek in the profit is Rs. 3300 (Option A).
To summarize, the steps to find the share of Vivek in the profit are:
- Calculate the investment and time period for each person.
- Find the ratio of profit sharing for each person by multiplying their investment and time period.
- Calculate the total ratio of profit sharing by adding the ratios of all persons.
- Find the share of Vivek by dividing his ratio by the total ratio and multiplying the result by the total profit.

 - Let the total profit be Rs. z.
Then, B’ share = Rs. 2z/3, A’s share = Rs. [z - 2z/3] = Rs. z/3
∴ A : B = z/3 : 2z/3 = 1 : 2.
Let the total capital be Rs. x and suppose B’s money was used for a months. Then,
[1/4 a x 15] / [3/4 a x y] = 1/2
⇔ y = [15 x 2 / 3] = 10.
Thus, B’s money was used for 10 months.
 - A : B : C = (20,000 x 24) : (15,000 x 24) : (20,000 x 18) = 4 : 3 : 3.
B's share = Rs. 25000 x 3 = Rs. 7,500. 10
 - Let the initial investments of A and B be 3x and 5x.
A : B : C = (3x x 12) : (5x x 12) : (5x x 6)
= 36 : 60 : 30
= 6 : 10 : 5.
 - Let B's capital be Rs. x.
Then, 3500 x 12 = 2 7x 3
14x = 126000
x = 9000.
- Suppose A invested Rs. 14a for 10 months and B invested Rs. 15a for b months. Then,
14a x 10 / 15a x b = 7/6 ⇒ b = 840 / 105 = 8
Hence, B invested the money for 8 months.
To solve this problem, we need to use the concept of the ratio of investments and the ratio of profits.
Let the initial investments of A and B be 14x and 15x, respectively.
Let the time for which A invested be 10 months and the time for which B invested be y months.
Since the profits are in the ratio 7:6, we can assume that the total profit is 13x. Therefore, A's profit would be (7/13) times the total profit and B's profit would be (6/13) times the total profit.
According to the question, A invested for 10 months and B invested for y months. Therefore, the ratio of the time for which they invested their money is 10:y.
We can now use the formula: Profit = (Investment × Time × Rate of Profit)/100
We know that A's profit was (7/13) times the total profit, and B's profit was (6/13) times the total profit. Therefore, we can write the following equations:
(7/13) × 14x × 10 = (6/13) × 15x × y
Simplifying this equation, we get:
y = (140/90) = 28/18 = 14/9 months
Therefore, B invested his money for 14/9 months, which is approximately 1.56 months, or 1 month and 16 days.
Since none of the options match this value, we can round it up to the nearest option, which is 8 months (Option D).
Hence, the correct answer is Option D, i.e., B invested his money for 8 months.
