30% of 1000 = 300 worked for 20 hours
Payment @ 5/hr
Total Payment = 300*20*5 = 30000

50 % of 1000 = 500 worked for 40 hours
Payment @ 5/hr
Total payment = 500*40*5 = 100000

Remaining 200 worked for 50 Hours

Payment for first 40 Hours @ 5 /hr
Payment = 200*40*5 = 40000
Payment for next 10 hr @ 7.5/hr
Payment = 200 * 10 * 7.5 = 15000

Total Payment = 30000+100000 + 40000 +15000 = 185000

Hence , answer is B

I did it in the following way.

\(30/100 * 1000 = 300\)
\(50/100 * 1000 = 500\)
\(20/100 * 1000 = 200\)

Hours are in same digits i.e. 20,40 and 50. Divide the digits by 10 and you will get 2,4, and 5. I reduced the number of employees to 3,5, and 2.
Now,
\(3*2*5 = 30\)
\(5*4*5 = 100\)
\(2*4*5 = 40\)
\(2*1*15/2 = 15\)

If we add them all it will be 185. The answer with 185 is only B.

(A) $180,000
(B) $185,000
(C) $190,000
(D) $200,000
(E) $205,000



300 workers: Payment $5 per hour; Total hours worked: 20. Total payment: 30 K
500 workers: Payment $5 per hour; Total hours worked: 40. Total payment: 100 K
200 workers:
Part a) Payment $5 per hour; Total hours worked: 40. Total payment: 40 K
Part b) Payment $7.5 per hour; Total hours worked: 10. Total payment: 15 K

30+100+40+15 = 185 K

B is the answer.

Remaining 200= 200 *40*5 + 200*10*7.5= 55000

Total= 185,000

B is the answer

(B) $185,000
(C) $190,000
(D) $200,000
(E) $205,000


So we have 300 workers who worked 20 hours, 500 workers who worked 40 hours, and the remaining 200 workers who worked 50 hours.

For the 300 workers who worked 20 hours, payroll was 300 x (20 x 5) = $30,000.

For the 500 workers who worked 40 hours, payroll was 500 x (40 x 5) = $100,000.

For the 200 workers who worked 50 hours, payroll was 200 x (40 x 5 + 10 x 7.5) = $55,000.

Therefore, the total payroll for all1000 workers is 30,000 + 100,000 + 55,000 = 185,000.

Answer: B
