Q:

Which best describes genetic mutations?

A) Genetic mutations that cause diseases are always passed on to offspring. B) Some inherited genetic mutations can be good for the offspring.
C) Different genetic mutations cause few forms of cancer. D) Somatic mutations can be inherited from parents or acquired during life.
 
Answer & Explanation Answer: B) Some inherited genetic mutations can be good for the offspring.

Explanation:

Mutations are accidents in the copying of DNA. A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms. 

 

Genetic mutations are accidental changes in the DNA in the germ cells or early in the formation of the embryo. These changes if they are in the germ cell will be passed on to other organisms formed by sexual reproduction or asexual reproduction. An example would be the golden delicious apple. A lost of genetic information due to a mutation resulted in a different color of fruit.

 

Genetic mutations that cause diseases are not always passed on to offspring.

Q:

The cost price of 40 Magazines is the same as the selling price of 'P' articles. If the profit is 25%, then the value of 'P' is:

A) 32 B) 40
C) 16 D) 30
 
Answer & Explanation Answer: A) 32

Explanation:

Let C.P. of each Magazine be Rs. 1

C.P. of P articles = Rs. P. 

S.P. of P articles = Rs. 40.

 

Profit = Rs. (40 - P)

 

Now, Gain% = ProfitC.P×100 = 40-PP×100 

 

Here 40-PP×100= 25

-->P = 32.

Q:

A train travels 325 km in 3.5 hours and 470 km in 4 hours. Find the average speed of train ?

A) 107 kmph B) 106 kmph
C) 72 kmph D) 76 kmph
 
Answer & Explanation Answer: B) 106 kmph

Explanation:

for average speed = Total Distance / Total Time Taken
Thus, Total Distance = 325 + 470 = 795 km
