While the first part focuses on numbers, cubic roots, decimal fractions, permutations and combinations, HCF and LCM, deafness and indices, and probability among the rest, this last section provides detailed information on tabulation of data, including pie charts and graphs .
The exercises after each chapter are well designed and have a complete and detailed explanation to help students understand whether the sums have been correctly done or not and also to have students understand how to get to the solution if one is stuck While trying to solve a particularly difficult sum.
For students appearing for the first time on the exams, the book also contains detailed documents from last year's resolved questions along with unresolved questions.
