Answers
Given : Salaries of Prakash : Prasad = 3 : 5
Salaries of Prasad : Pravin = 2 : 3
Pravin = 9000 + Prakash-------------(1)
Solution : Prakash/Prasad = 3/5-----------------given
so Prakash = (3/5)*Prasad------------(2)
& Prasad/Pravin = 2/3-------------------given
so Pravin = (3/2)*Prasad---------------(3)
Put equation 2&3 in equation 1
(3/2)*Prasad = 9000 + (3/5)*Prasad
(9/10)*Prasad = 9000
So, Prasad = 10000
Prasad's salary is 10000
Prasad Salary = 10000
Step-by-step explanation:
The ratio of the salaries of Prakash and Prasad is 3 : 5
Let sat Prasad Salary = 10P
Then Prakash Salary = (3/5) * 10P = 6P
The ratio of the salaries of Prasad and Pravin is 2 : 3
Prasad Salary = 10P
=> Pravin Salary = (3/2) * 10P = 15P
Pravin's salary is rs 9000 more than that of prakash
=> 15P = 6P + 9000
=> 9P = 9000
=> P = 1000
=> 10P = 10000
Prasad Salary = 10000
