D and E start a business with equal investments. After 4 months, D adds Rs. 10,000 more. At the end of 1 year, if the total profit is Rs. 33,000, and E's share is Rs. 15,000, what was their initial investment?

The correct answer is
Rs. 33,333.33

Profit Ratio Calculation

The total profit is Rs. 33,000. E's share is Rs. 15,000. Therefore, D's share is:

D's Profit = Total Profit - E's Profit

D's Profit = Rs. 33,000 - Rs. 15,000 = Rs. 18,000

The ratio of their profits is D:E = 18,000 : 15,000. Simplifying this ratio by dividing both by 3,000 gives:

Profit Ratio (D:E) = 6 : 5

Investment Calculation

Let the initial investment made by both D and E be Rs. x.

The business duration is 1 year (12 months).

  • E's Investment: E invested Rs. x for the entire 12 months. Total investment by E = $x \times 12 = 12x$ months.
  • D's Investment: D invested Rs. x for the first 4 months. After 4 months, D added Rs. 10,000. So, for the remaining 8 months (12 - 4 = 8), D invested Rs. $(x + 10,000)$. Total investment by D = $(x \times 4) + ((x + 10,000) \times 8)$ = $4x + 8x + 80,000$ = $12x + 80,000$ months.

Equating Ratios and Finding Initial Investment

The ratio of total investments must be equal to the ratio of profits.

Investment Ratio (D:E) = Profit Ratio (D:E)

$\frac{12x + 80,000}{12x} = \frac{6}{5}$

Cross-multiply to solve for x:

$5 \times (12x + 80,000) = 6 \times 12x$

$60x + 400,000 = 72x$

Subtract $60x$ from both sides:

$400,000 = 72x - 60x$

$400,000 = 12x$

Divide by 12:

$x = \frac{400,000}{12}$

$x = \frac{100,000}{3}$

$x \approx 33,333.33$

The initial investment was approximately Rs. 33,333.33.
