Question

in an examination the ratio of a number of successful to unsuccessful candidate is 5:2 and the total number of candidate is 4564​

Answer 1

Let successful candidates be 5X

Let unsuccessful candidates be 2X

Total no. of candidates. is 4564

Now, if we add Successful and Unsuccessful candidates, we will get total no. of candidates. So the sum of  5X and 2X will be 4564.

By putting these in an equation, we get

5X + 2X = 4564

=> 7X = 4564

=> X = $\frac{4564}{7}$

= X =  652

Unsuccessful Candidates = 2X = 2 × 652 = 1304 Candidates

Successful Candidates = 5X = 5 × 652 = 3260 Candidates
