Question
Number of faculties in Physics and Biology in an
institute is in the ratio of 2:3 respectively. If 60 more faculties join Physics, while 32 more faculties join Biology, the respective ratio becomes 3:4. Originally what was the total number of faculties in both together? ÂSolution
Let the original number of faculties in Physics and Biology be 2x and 3x respectively According to the question,  => (2x + 60)/(3x + 32) = 3/4 => 9x + 96 = 8x + 240 => x = 144 Original number of faculties = 2x + 3x = 5x = 5 × 144 = 720
