PYQ Practice Set 1
Thirty-five interest questions from real SSC papers: 12 from CGL 2025, 3 from Selection Post 2025, 7 from CGL 2024, 7 from CGL 2023 and 6 from CGL 2022. The paper is named at the end of each question. Most of the set is simple interest (two amounts, a sum lent at two rates, a sum becoming n times), and the compound interest questions come near the end. The last three are from Tier 2. SSC's wording is often long and a little odd, so pick out P, R and T before you calculate. Allow about 25 minutes, around 40 seconds a question, and do them all before you look at the working.
