Premium Simple Interest | Maths Codebreaker | Answers Included

PREMIUM RESOURCE - available to purchase; this is not a free download.

Find interest, final balances, principal, rates and time using simple interest.

This Premium paid resource contains one complete A4 pupil worksheet with 20 questions and a matching answer page with workings, plus a product-family guide. Pupils solve the maths, match answers to letters in the code grid and decode the hidden words.

Difficulty: Level 5 of 10 within this range (1 is easiest; 10 is most demanding). These levels are a guide to relative challenge, not GCSE grades.

Three questions from this worksheet:
1. £500.00 is deposited in a savings account paying 1% simple interest per year for 5 years. Find the interest earned in pounds.
2. £1000.00 and £1200.00 are invested at 8% simple interest per year for 5 years. Find the difference in interest, in pounds.
3. £1500.00 earns £30.00 in simple interest over 1 year. Find the annual interest rate as a percentage.

Use for focused practice, consolidation, homework or a lesson activity after teaching the method. Print the pupil page for learners and retain the answer page for checking. Follow the rounding and unit instructions on the sheet.
