The average of five consecutive odd numbers is 55. What is the difference between the highest and lowest numbers?
[ "2", "8", "9", "5" ]
B
Explanation : Let the numbers be x, x + 2, x + 4, x + 6 and x + 8. Then, (x + (x + 2) + (x + 4) + (x + 6) + (x + 8))/5 = 55 5x + 20 = 275 x = 255/5 = 51. So, required difference = (51 + 8) 51 = 8 Answer : C

The present average age of a family of five members is 26 years. If the present age of the youngest member in the family is ten years, then what was the average age of the family at the time of the birth of the youngest member ? (Assume no death occurred in the family since the birth of the youngest?
[ "20 years.", "30 years.", "20 years.", "80 years" ]
A
Present total age of the members = 26(5) = 130 years. Present age of the youngest member = 10 years Present total age of the remaining four members = 130 -10 = 120 years Their average age at the time of the birth of the youngest member = [120 - (4 * 10)] / 4 = 30 - 10 = 20 years. Answer: C

What happens to evolution when equilibrium is reached within the genes of the population?
[ "it stops occurring", "it starts over", "it accelerates", "it goes backwards" ]
A
If balance, or equilibrium, is to be maintained, there must be no outside influences on the stones. Equilibrium can also be maintained within a population's genes; that means, no evolution can occur. But outside influences usually prevent equilibrium from staying established.
