If x:y = 3:5 then find (1/x 1/y): (1/x -1/y)?? Opt a) 2 b)4. c) 6. d)...
Solution:
Given, x:y = 3:5
Let's assume x = 3k and y = 5k, where k is a constant.
Then, (1/x) + (1/y) = (5+3)/(15k) = 8/15k
And, (1/x) - (1/y) = (5-3)/(15k) = 2/15k
Therefore, ((1/x) + (1/y))/((1/x) - (1/y)) = (8/15k) / (2/15k) = 4
Hence, the answer is option (b) 4.
Explanation:
To solve this question, we need to use the concept of ratios and fractions. We are given that x:y = 3:5. So, we can assume that x is 3k and y is 5k, where k is a constant. This will make the ratio of x and y equal to 3:5.
Now, we need to find the value of ((1/x) + (1/y))/((1/x) - (1/y)). To do this, we can simply substitute the values of x and y in the given expression and simplify it. We get ((1/x) + (1/y))/((1/x) - (1/y)) = (8/15k) / (2/15k) = 4.
Therefore, the answer to the question is 4.
