The book is good but some mistakes in answers in problems on Trains in Quantitative aptitude..My advice is to provide answers with explanations for Practice Paper which is given at the end of book.on june 3 i wrote United insurance exam i find the questions which are in Practice paper not exactly the same questions i find that model questions.so please solve the practice paper and it is useful for students who purchase it.Please go through all the book and rectify mistakes.
