Eighteen original bilingual questions on simple interest, compound interest, rate-period matching, growth, depreciation and basic reverse cases. Free untimed learning review: +1 correct, 0 incorrect or unattempted, no negative marking and no pass cutoff. Full solutions and every-option explanations. This is module practice, not a full CBT mock. This is an original 18-question review of Simple and Compound Interest, not an official past paper or a full RRB CBT mock. It is free and untimed. Choose one answer A–D for each question. A correct answer earns 1 mark; an incorrect or unattempted answer earns 0. There is no negative marking and no pass cutoff. Your result records this practice attempt and does not predict selection or exam performance. First identify the model and requested quantity, then match the rate with its period. A nominal annual rate is divided among periods only when the question explicitly states that convention. A rate already quoted per half-year or quarter is used for that period without dividing it again. The stated models have no extra deposits, withdrawals, repayments, fees or taxes unless the question says otherwise. Growth and depreciation quantities are hypothetical. Calculate exactly; every required numerical answer has a terminating value. Attempt the questions before opening the explanations. Each explanation includes the solution, a check and a diagnosis of every option.
