Finding The Magical Number

What was the teaser? 

We need to first find LCM of 2,3,4,5 & 6. It's 60. Had there been only 6 men then 61 would have been right answer. But on arrival of 7th man all mangoes distributed. So we need to find such number which is divisible by 7 & that number - 1 is divisible by 60.

Smallest such a number is 301. So they had 301 mangoes!

Checking Available Networks In All Phones

This I used to check available networks in the region before purchasing new SIM. I had found this in my first feature phone! 

1. Go to the SETTING.

2. Select PHONE.

3. Enter into NETWORK.

4. Change Operator selection to MANUAL.

5. Wait till phone scans all available networks.

6. Restore Operator Selection to AUTOMATIC otherwise it would keep asking to choose network if you go out of range for a moment.
