Answer:
380.
Step-by-step explanation:
Given:
Total number of employees at Gallicum Enterprises are in the ratio,
J : k : L = 1 : 3 : 5 for some time.
Last month, 20 new J employees were hired, and no employees left and the new ratio of J to K is now 1 : 2.
Question asked:
What is the new total number of employees at Gallicum Enterprises ?
Solution:
<u>As given, J : K : L = 1 : 3 : 5 </u>
<em><u>So, J : K = 1 : 3 </u></em>
As last month, 20 new J employees were hired, new ratio of J to K is now
1 : 2.
So,
Dividing equation 1 and 2,
By cross multiplication:
Subtracting both sides by
From equation 1.
By cross multiplication:
As given, J : K : L = 1 : 3 : 5
So, K : L = 3 : 5
By cross multiplication:
Dividing both sides by 3
<em>New total number of employees after hiring 20 new J employees :</em>
New J + K + L<u> =</u> (New J = J + 20 = 40 + 20 = 60 )
60 + 120 + 200 = 380
Therefore, the new total number of employees at Gallicum Enterprises is 380.
