In case of stock1, if he invest Rs.105, he will get a dividend of Rs.12 (assume face value = 100)
In case of stock2, if he invest Rs.88, he will get a dividend of Rs.8 (assume face value = 100)
ie, if he invest Rs.(88*12)/8, he will get a dividend of Rs.12
Required ratio = 105 : (88 × 12)/8 = 105 : (11 × 12) = 35 : (11 × 4) = 35 : 44

A man invests some money partly in 12% stock at 105 and partly in 8% s...
Investment in 12% stock at 105
Let's assume the man invests a certain amount of money in the 12% stock at 105. The dividend earned from this investment can be calculated as follows:
Dividend = (12/100) * Investment
Investment in 8% stock at 88
Similarly, the man also invests a certain amount of money in the 8% stock at 88. The dividend earned from this investment can be calculated as follows:
Dividend = (8/100) * Investment
Equal dividends from both stocks
The question states that the man wants to obtain equal dividends from both investments. Therefore, we can equate the two dividend equations:
(12/100) * Investment in 12% stock = (8/100) * Investment in 8% stock
Simplifying this equation, we get:
12 * Investment in 12% stock = 8 * Investment in 8% stock
Let's assume the investment in the 12% stock is x and the investment in the 8% stock is y. Therefore, we have the following equation:
12x = 8y
Solving for x, we get:
x = (8/12) * y
x = (2/3) * y
Ratio of investments
The question asks for the ratio of investments made in the two stocks. From the equation above, we know that x = (2/3) * y. Therefore, the ratio of investments can be written as:
x : y = (2/3) : 1
To make the ratio of the investments in the required format, we can multiply both sides of the equation by 3:
3x : 3y = 2 : 3
Now, we can rewrite the ratio in terms of the given options:
3x : 3y = 35 : 44 (since 35/44 is approximately equal to 2/3)
Therefore, the correct ratio of investments is 35 : 44, which corresponds to option D.
