Here is the critical truth: S. Chand never published a single, official, comprehensive solution manual for the main Khurmi & Gupta textbook (ISBN 971) to the general public. Instead:
Thus, many searches for "solution manual of theory of machine by rs khurmi gupta 971" lead to third-party, user-uploaded content.

The search for the "solution manual of theory of machine by rs khurmi gupta 971" is a wild goose chase. It is a digital ghost created by student demand that the publisher never officially fulfilled.
Advice to the student: Stop searching for the PDF. Instead, solve the problems using the solved examples within the "971" text as your guide. For the unsolved exercises, form a study group. The process of struggling through the kinematics of a Whitworth quick return mechanism or the dynamics of a Porter governor without a manual is, ironically, the only way to truly learn Theory of Machines.
The manual does not exist. The knowledge does. Go build it. Here is the critical truth: S
Problem: A crank and rocker mechanism has a crank length of 100 mm and a rocker length of 200 mm. The distance between the fixed pivots is 300 mm. If the crank rotates at a uniform speed of 60 rpm, determine the velocity of the rocker tip when the crank is at 45 degrees from the inner dead center.
Solution Approach (Standard Khurmi Method):
Calculate Angular Velocity of Crank ($\omega$): $$ \omega = \frac2 \pi N60 = \frac2 \pi \times 6060 = 6.28 , \textrad/s $$ Thus, many searches for "solution manual of theory
Calculate Linear Velocity of Crank Pin ($v_p$): $$ v_p = \omega \times r = 6.28 \times 0.1 = 0.628 , \textm/s $$
Graphical Solution Method:
Result: Using trigonometry or the diagram, you would determine the velocity of the rocker tip ($v_q$). (Note: In Khurmi's manual, specific numerical answers are derived using precise trigonometric calculations or scaled drawings.)
