Solved problems of higher algebra – from hall and knight

"A K Sen is a mechanical engineer, having served in distinct govt. and private organisations. Having an interest in mathematics, he enjoys solving such problems. During this venture, he found out that Hall & Knight Algebra does not have any solved book in the market. Hence, he took this job of solving 20 important chapters of the interests of common students and solved them as easily as possible and published them. ""I hope students will benefit from this venture; in that case, my effort will have succeeded and bring me satisfaction. If a student finds further improvement is required, they may communicate with me, all suggestions will be attended to."" -A K Sen"
