Answer 1

Answer:

120 km

Step-by-step explanation:

Given  

Arjun runs 8 kilometres everyday except on alternate Saturdays and Sundays when he runs 12 km how many kilometre does he run in 2 weeks

Given Arjun runs 8 kms everyday except alternate Saturday and Sunday he runs 12 km.

 So first week Arjun runs 8 km x 7 days = 56 km

Second week he runs 8 km x 5 days + 12 km x 2 days  

                                  = 40 + 24 = 64 km

Now in two weeks he runs 56 km + 64 km = 120 km

Answer 2

Answer:

Arjun runs 120 kilometres in 2 weeks

Step-by-step explanation:

Given that Arjun runs 8 kilometres everyday except on alternate Saturdays and Sundays, when he runs 12 kms

We need to calculate the kilometres run in 2 weeks.

In 2 weeks, lets first  exclude alternate Saturdays and Sundays.

Thus, in span of 2 weeks, Saturday and Sunday will be considered only one

Number of days in 2 weeks = 14

Number of days in 2 weeks excluding Saturdays and Sundays = 14 - 2 = 12

Lets us first calculate the distance when Arjun runs 8 kilometres

Now, Distance run in 1 day = 8 kms

Distance run in 12 days = 8 × 12 = 96km

Now, distance when Arjun runs 12 kilometres

Arjun runs 12 km on 2 days, thus distance covered = 12 × 2 = 24 kms

Total kilometres run by Arjun in 2 weeks = (96 + 24)kms = 120 kms
