A man's regular pay is Taka 30 per hour up to 40 hours Overtime is twice the payment for regular time If he was paid Taka 1680, how many hours overtime did he work ?

A 8

B 16

C 28

D 48

Correct Answer: Option A

solution: Normal payment = 30 \( \times \) 40 = 1200

Extra payment = 1680 - 1200 = 480

Overtime payment for 1 hour is 30 \( \times \) 2 = 60

So, Overtime work = 480/60 = 8 hrs.
