      Solution

      Let the total number of people in the office be โ€˜100xโ€™ Number of males in the office = 100x ร— 0.37 = โ€˜37xโ€™ Number of females in the office = 100x โ€“ 37x = โ€˜63xโ€™ Total number of married people in the office = 100x ร— (3/5) = โ€˜60xโ€™ Total number of unmarried people in the office = 100x ร— (2/5) = โ€˜40xโ€™ Number of married males in the office = 60x ร— (8/15) = โ€˜32xโ€™ Number of married females in the office = 60x โ€“ 32x = โ€˜28xโ€™ Number of unmarried females in the office = 63x โ€“ 28x = โ€˜35xโ€™ According to question: 35x = 112 x = 3.2 So, total number of people in the office = 100 ร— 3.2 = 320
