The only command that shows which access lists have been applied to an interface is show ip interface Ethernet 0. The command show access-lists displays all configured access lists, and show ip access-lists displays all configured IP access lists, but neither command indicates whether the displayed access lists have been applied to an interface.

Seats for Mathematics, Physics and Biology in a school are in the ratio 5 : 7 : 8. There is a proposal to increase these seats by 40%, 50% and 75% respectively. What will be the ratio after increased seats?
  • a)
    2 : 3 : 4
  • b)
    6 : 7 : 8
  • c)
    6 : 8 : 9
  • d)
    None of these
Correct answer is option 'A'. Can you explain this answer?

Originally, let the number of seats for Mathematics, Physics and Biology be 5x, 7x and 8x respectively.
Number after increased seats are (140% of 5x), (150% of 7x) and (175% of 8x).
⇒ (140 / 100 x 5x), (150 / 100 x 7x) and (175 / 100 x 8x)
⇒ 7x, 21x / 2 and 14x.
∴ the required ratio
= 7x : 21x / 2 : 14x
⇒ 14x : 21x : 28x
⇒ 2 : 3 : 4.
