Pipe A can fill a tank in 15 minutes, while pipe B can empty the completely filled tank in 20 minutes. Initially, pipe A is opened and after 5 minutes pipe B is also opened. In how much time (in minutes) will the remaining tank be filled completely?
If 1 is added to the first digits and 1 is subtracted from the last digits of each of the following numbers, then in how many numbers will the first digit be exactly divisible by the last digit?
242, 657, 864, 264, 674, 218, 845
Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(28, 33, 48)
(67, 72, 87)
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 1–3 → Operations on 13 such as adding/deleting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
