Question
Number of faculties in Physics and Biology in an
institute is in the ratio of 5:7 respectively. If 45 more faculties join Physics, while 24 more faculties join Biology, the respective ratio becomes 3:4. Originally what was the total number of faculties in both together?Solution
Let the original number of faculties in Physics and Biology be 5x and 7x respectively According to the question, => (5x + 45)/(7x + 24) = 3/4 => 21x + 72 = 20x + 180 => x = 108 Original number of faculties = 5x + 7x = 12x = 12 × 108 = 1296
