Solution

Q1. Ans(2)
Q2. Ans(3)
Q3. Ans(2)
Q4. Ans(4)
Q5. Ans(2)
Sol. (6 -10):
Let total employees in HR, Marketing and Accounts department be 4x, 9x & 2x respectively.
Let numbers of female employees in HR department be y.
So, number of female employees in Marketing department = y + 5
ATQ,
y + y + 5 = 45
2y = 40
y = 20
And, 4x + 9x + 2x + 55 = 205
15x = 150
x = 10
Hence, number of female employees in Operations department = 2 × 10 + 15 = 35
Now,
Male employees in Operations department = 55 – 35 = 20
Male employees in HR department = 4x – y = 40 – 20 = 20
Male employees in Marketing department = 9x – (y + 5)
= 90 – 25 = 65
Now,
Let male employees in Accounts department be ‘a’.
Hence, female employees in Accounts department = 2x – 15 = 20 – 15 = 5
Q6. Ans(3)
Q7.Ans(4)
Q8. Ans(1)
Q9. Ans(2)
Required difference = 90 – 55 = 35
Q10. Ans(2)
