Scientific paper

LRS Bianchi type-I space-time filled with perfect fluid is considered here with deceleration parameter as variable. The metric potentials A and B are functions of x as well as t. Assuming B'/B = fx_, where prime denotes differentiation with respect to x, it was found that A=(l'/l)B and B=lS(t), where l=f(x) and S is the scale factor which is a function of t only. The value of Hubble's constant H0 was found to be less than half for non-flat model and is equal to 1.3 for a flat model.
