Is it possible to solve these without algebra? These are P5 Questions from past year exam papers for SA1.

I believe algebra is only taught in P6, so just curious how come these questions can be asked for SA1 of P5 :?

Ken and Patrick had $625 at first. After buying some books, the amount of money Ken has left is 4 times the amount of money he spent and the amount of money Patrick has left is 5 times the amount of money he spent. Find the amount of money Patrick had at first if they have a total of $510 left.

Dear maths guru


Please help me with the following question:

1) The distance between village A and Village B is 360km. John drove from Village A to Village B and completed the journey in 4 hours. Peter drove from Village B to Village A and completed the journey in 6 hours. If both of them started the journey at 9.30am, at what time would they pass each other?

2) Chive, Parsley and Thyme bought a present for their mother. Chive paid 1/3 of the total amount paid by Parsely and Thyme. Parsley paid 1/3 of the total amount paid by Chive and Thyme. If Thyme paid $60 more than Parsely, how much did the present cost?

3) The ratio of the number of $5 notes to the number of $10 notes that Libby had was 5:3. She bought a dress for $65 and paid it with 7 pieces of $5 notes and some $10 notes. The ratio of the number of $5 notes to the number of $10 notes Libby had left was 3:2.
How much did Libby have at first?

Thank you
