Which prepositions do you think go in those blanks?

I'll be glad to check your answers.
1.in ?

2.on ?
1. no
Better prepositions are by or with.

2. on is right.
So which will it be ? By or With ? one answer ?
Either one is correct. Use the one you want.

As you know, English prepositions don't always have exact meanings. Often two or more can be used interchangeably.
Thank you :)
You're welcome.

You can say "by cheque" or "with a cheque."
