In an office, the ratio of the number of males to number
of females is 11:8. If 3 males joined the class and 4 females left the class, then the ratio of number of males to that of females in an office would become 3:2. Find the actual number of females in the class.Solution
Let initially the number of males and females in an office be 11x and 8x respectively. According to the question, => (11x + 3) : (8x – 4) = 3:2 => 22x + 6 = 24x – 12 => x = 9 Therefore, number of females in an office = 8 x 9 = 72
