Question

An Advertising agent goes on vacation to three countries, India, New Zealand and Australia. He spend three times the number of days in New Zealand than he does in Australia and five days longer in India than in Australia. If his total vacation duration is 40 days, how many days he spend in Australia?

Answer 1

Answer:

7 days

Step-by-step explanation:

Let the number of days the Advertising agent sent in India = x

Let the number of days he spent in New Zealand = y

Let the number of days he spent in Australia = z

Given;

He spent three times the number of days in New Zealand than he does in Australia

=> y = 3z

Also given;

He spent five days longer in India than in Australia

=> x = 5 +z

The total number of days of his vacation = 40

x + y + z = 40

5 + z + 3z + z = 40

5 + 5z = 40

5z = 35

z = 7

Therefore, the number of days he spent in Australia = 7 days
