Ans 200


Step by step:

\(0.7*800=560\) employees have serviced more than 10 years;

We are told that after \(y\) of those employees leave the company the # of employees who have serviced more than 10 years (\(560-y\)) become 60% of a new total, which will be \(800-y\), so: \(0.6*(800-y)=(560-y)\) --> \(y=200\).

Hope it's clear.

Ans is 200 employees
let y employees retire so now 560-y employees remain. So total no of employees becomes 800-y
560-y/800-y = 60/100
on solving we get y =200

Of the 800 employees in a certain company, 70% have serviced more than 10 years. A number of y of those who have serviced more than 10 years will retire and no fresh employees join in. What is y if the 10 years employees become 60% of the total employees?

Solution:

TOTAL 10 YRS
Original: 800 560
New: 800-y 560-y

560-y = .6 (800 -y)
560-y = 480 - .6y
80 = .4y
800/4 = y
y= 200

Answer: 200

Total Employees = 800

70% = 560

> than 10 Yrs ......... Others ............ Total

560 ..........................240 ..................... 800

Total y employees retire; new figures would be

560-y ................................. 240 ....................... 800-y

Given that post retirement of y employees; > than 10yrs employees would be 60% of total

This also means that the other employees are 40% of the total (Reason behind this step is to have the variable y only at one side of the equation)

Setting up the equation

\(240 = \frac{40}{100} (800-y)\)

y = 200

Answer = 200


ARPS: Can you please provide the OA for this question?
