Correct Answer - Option 1 : Rs 680
Given:
The rate of washing cloth in the laundry is S following:
i) up to 5 clothes and less than 8 clothes - Rs 20
ii) up to 12 clothes and less than 15 clothes - Rs 40
iii) up to 20 clothes - Rs 42
iv) More than 15 clothes and less than 18 clothes - Rs 2 discount on each clothes
Calculation:
A man has given 17 clothes.
So, he will pay Rs. 42 for each clothes and get Rs 2 discount on each clothes
⇒ Rs. (42 × 17) - Rs. (17 × 2)
⇒ Rs. (714 - 34)
⇒ Rs. 680
∴ The man will pay Rs. 680 for washing.
Here cloth is more than 15 so we have to subtract the discounted price
