Average salary of clerk = 3k
Average salary of manager = 6k
Average salary of executives = 10k
If the average salary of clerk and manager is 4K.
Then, the ratio of clerk to manager = 2:1
If the average salary of clerk and executive is 5k.
Then, the ratio of clerk to executive is 5: 2.
If we multiply the first ratio of clerk : Manager by 5, we get 10 : 5
If we multiply the second ratio by 2, we get clerk to executive is 10 : 4
Thus, the ratio of Clerk : Manager : Executive = 10 : 5 : 4

say num of clerks = x
num of managers = y
num of executives = p
avg salary of clerk = 3000
avg salary of managers = 6000
avg salary of executives= 10000
now avg salary of clerks and managers = 4000
total clerks and managers = x + y
sum of clerks salary = 3000x
sum of managers salary = 6000y
3000x + 6000y / (x+y) = 4000
3000x + 6000y = 4000x + 4000y
x=2y
y = x/2
avg salary of clerks and executives = 5000
sum fo executives salary = 10000p
total clerks and executives = x + p
3000x + 10000p /(x+p) = 5000
3000x + 10000p = 5000p + 5000x
5p = 2x
p = (2/5) x
the ratio of x:y:p = x: (x/2) : (2/5)x
10x : 5x : 4x
