1.	A mass M is suspended from a spring of negligible mass. The spring is pulled a little and then released so that the mass executes simple harmonic oscillations with a time period T. If the mass is increased by m then the time period becomes \[\left( \frac{5}{4}T \right)\]. The ratio of \[T\frac{p}{p-1}\] is [CPMT 1991]
