Equal masses of two samples A and B of charcoal are burnt and the activity of resulting carbon dioxide from two samples is measured. The gas from sample A gives $10$ $^{4}$ counts per month and that from sample B gives $2.5$ x $10$ $^{3}$ counts per month. The age difference of two samples is ( half life of $C^{14}$ is $5730$ years)

The counting rate of disintegration of radioactive source at $t = 0$ second was $1600$ counts per second and at $t = 8$ seconds was $100$ counts per second. The counting rate observed as counts per seconds, at $t = 6$ second would have been
