Practicing Success
If the ratio of selected to unselected candidates was 14 : 25. If 35 less had applied and 10 less selected, the ratio of selected to unselected would have been 3 : 5. What is the Number of candidates who had applied for a job? |
200 175 275 195 |
195 |
Let the number of selected candidate be 14x and the number of unselected candidates be 25x, number of candidates is 195 who had applied for a job. So, the total number of applied candidates is 14x + 25x = 39x According to the question, If 35 less applied, then resulting number of candidates applied is (39x - 35) And 10 less candidates got selected, then the resulting no. of candidates selected is (14x - 10). So, the resulting no. of unselected candidates is (applied - selected) ⇒ (39x - 35) - (14x - 10) ⇒ 25x - 25 Now, the given ratio of resulting selected to the resulting unselected candidates is 3 : 5 So, \(\frac{14x - 10}{25x - 25}\) = \(\frac{3}{5}\) ⇒ x = 5, So, the number of candidates who had applied = 39x ⇒ 39 x 5 = 195. Therefore number of candidates who applied for job are 195. |
