On a given day, a bank had 16000 cheques returned by customers. Inspection of the first 800 cheques indicated that 100 of those 800 had errors and were therefore the available immediately for data processing. On this basis, hwo many cheques would be available immediately for data processing on that day?

1. It is given for every 800 cheques 100 are error
   so (800-100) 700 error free
   total 16000 cheques
   so dividing them into 800 in each we get (16000/800) 20
   so 20 sets of cheques (each 800) where each set has 700
   error free
   so 20*700 14000 is the answer

2. Out of 800 cheques 100 are for data processing.
   Out of 16000 cheques = (100/800)*16,000 = 2000 cheques
