1. 790 2. 610 3. 500 4. 1020​

Answer 1

Answer:

This is what I feel

Step-by-step explanation:

Let the total number of workers = x

According to the question,

60x=12×400+56(x−12)

=>60x−56x=4800−672

=>4x=4128=>x=1032

your options are wrong I guess..

Answer 2

Step-by-step explanation:

total workers = x

officers = 12

clerks = x - 12

60x = 12*400 + 56 ( x - 12)

→ 60x = 4800 + 56x - 672

→ 4x = 4128

→ x = 4128 / 4

→ x = 1032

now clerks = x - 12 = 1032 - 12 = 1020

so ans is no. 4
