1 MATHEMATICS (51) CLASS X There will be one paper of two and a half hours duration carrying 80 marks and Internal Assessment of 20 marks. The paper will be divided into two sections, Section I (40 marks), Section II (40 marks). Section I: Will consist of compulsory short answer questions. Section II: Candidates will be required to answer four out of seven questions. 1.Commercial Mathematics (i)Goods and Services Tax (GST) Computation of tax including problems involving discounts, list-price, profit, loss, basic/cost price including inverse cases. Candidates are also expected to find price paid by the consumer after paying State Goods and Service Tax (SGST) and Central Goods and Service Tax (CGST) - the different rates as in vogue on different types of items will be provided. Problems based on corresponding inverse cases are also included. (ii)Banking Recurring Deposit Accounts: computation of interest and maturity value using the formula: =(+ 1)2 × 12×100MV = P ×n + I 2.Algebra (i)Linear Inequations Linear Inequations in one unknown for x ∈N, W, Z, R.
