If a woman is paid Tk. c per hour she works up to 8 hours and is paid double for every hour she works after 8 hours, how many hours she worked if she was paid Tk. 18c?
সঠিক উত্তর: Option B
She was paid 8c for 8 hour so , remaining (18c-8c) =10 c after 8 hour she was paid double =2c so ,she worked for = 10c/2c = 5 hour so, total hour = (8+5)=13 hour
