Directions: The line graph shows the percentage of people using debit card to pay the bill, percentage of people getting 10% cashback using debit card out of the total people using debit card for payment, percentage of people getting 2% cashback using cash payments out of the total people using cash for payment while paying their bills either through debit card or cash only in four different restaurants (P, Q, R and S) on any day. Read the line graph carefully and answer the following questions.
Note: (i) Cash back is given to customers in the given manner.
1. Debit card users get 10% cashback
2. Cash payments users get 2 % cashback
(ii) Total people who paid bill using debit card = number of people getting 10% discount + number of people did not get any discount using debit card
(iii) Total people who paid bill using cash = number of people getting 2% discount + number of people did not get any discount using cash

In restaurant P, 400 customers are using debit card but not getting cashback, then find the number of people getting cashback in restaurant P?
