A courier agent has to deliver post in 3 streets.

Each street has 5 houses.

He takes 2 min to deliver letter in each house and 5 min to travel between each house in each street.

He takes 20 min to go to the next street.

If in each street only 2 houses has to be delivered, then:

Time taken for delivery in 1st street and going to 2nd street = (2 + 5 + 2 + 20) minutes

= 29 minutes

Time taken for delivery in 2nd street and going to 3rd street = (2 + 5 + 2 + 20) minutes

= 29 minutes

Time taken for delivery in 3rd street = (2 + 5 + 2) minutes

= 9 minutes

Therefore, total time taken by the courier agent = (29 + 29 + 9) minutes

= 67 minutes

So, 67 minutes is the total time taken to deliver the letters.

Hence, ‘67 minutes’ is the correct answer.
