Question

10. In an office 10 clerks get a salary of 2500 each and 5 officers get a salary of *3500 each. Find
the
average salary of the employees in the office.​

Answer 1

Answer:

Average salary of the employees in the office = ₹2833

Step-by-step explanation:

Given :

10 clerks get a salary of 2500 each.

5 officers get a salary of 3500 each.

Now,

Average salary of the employees :

= (Sum of total salary of the employees)/(total no. of employees)

= (10 × 2500 + 5 × 3500)/(10 + 5)

= (25000 + 17500)/(15)

= 42500/15

= 2833 (approx.)

Answer 2

$\large\underline{\underline{\textsf{\maltese\:\: {\red{Given :}}}}}$

☞ 10 clerks get a salary of Rs 2500 each.

☞ 5 officers get a salary of Rs 3500 each.

$\large\underline{\underline{\textsf{\maltese\:\: {\red{To Find :}}}}}$

☞ Average salary of the employees in the office.

$\large\underline{\underline{\textsf{\maltese\:\: {\red{Solution :}}}}}$

$\blue\bigstar\bf{ \;Average = \dfrac{Sum \; of \; observations}{Number \; of\; Observations}}$

⨳ Salary of 1 clerk = Rs 2500

⇒ Salary of 10 clerks = 10 × Rs 2500

⇒ Salary of 10 clerks = Rs 25000

⨳ Salary of 1 officer = Rs 3500

⇒ Salary of 5 officers = 5 × Rs 3500

⇒ Salary of 5 clerks = Rs 17,500

⨳ Total number of employees = Number of clerks + Number of officers

⇒ Total number of employees = 10 + 5

⇒ Total number of employees = 15

Average salary of the employees in the office

= $\sf \dfrac{Salary \; of \; 10 \; clerks + Salary \; of \; 5 \; clerks}{Total \; number \; of \; employees}$

= $\sf \dfrac{Rs 25000 \; + \; Rs 17,500}{15}$

= $\sf \dfrac{Rs \; 42,500}{15}$

≈ $\bf{R_s \; 2,833}$

∴ Average salary of the employees in the office is $\underline{\bf{R_s \; 2,833 \; (approximately)}}$.
