Questions by Topic Open the Biology bookletsTop grades are built on one habit: practising real exam questions, topic by topic, until nothing on the paper can surprise you. We’ve taken years of past papers, right up to the June 2025 exams, and sorted every question into its topic, easiest first, with the official mark scheme built into the same booklet.

1.2.3 Price, Income and Cross Elasticities of Demand
2 (a) In 2021, a bakery sold 2.5 million sausage rolls per week at the price of £1.00 each. In 2022 the price increased to £1.20. The price elasticity of demand was estimated to be −0.2.
Calculate the new quantity of sausage rolls sold per week in 2022 after the price increased, ceteris paribus. (3)

Identifies the formula for PED (may be implicit)1
−0.2 = x ÷ +20, so quantity demanded falls 4%1
4% of 2.5m is 100 000, so 2.4 million1
