E.coli has only 4.6 × 10 6 base pairs and completes the process of replication within 18 minutes, then the average rate of polymerisation is approximately- (1) 2000 base pairs/second (2) 3000 base pairs/second (3) 4000 base pairs/second (4) 1000 base pairs/second

Taps A and B can fill a tank in 15 minutes and 10 minutes, respectively while tap C can empty the full tank in x minutes. If all the three taps are opened together, the tank is filled completely in 8 minutes. Tap C can alone empty {:(3)/(8):} th part of the tank in:

Two vessels of different materials are identical in size and wall-thickness. They are filled with equal quantities of ice at 0^(@)C . If the ice melts completely in 10 and 25 minutes respectively, compare the coefficients of thermal conductivity of the materials of the vessels.

After travelling 25 km the speed of the car increases by 1/4th of its original speed, due to this the car reaches 30 minutes earlier on its destination. If the speed of the car increased 10 km before, then it reached to its dentination 32(2)/(5) mintues earlier. The find the speed of car :
