17. Since the speed is uniform, the distance is proportional to the time and the path taken by the man is the perimeter of a right angled triangle with sides in the ratio 15 : 8 : 17 where 17 = by Pythagoras theorem.
    Hence the time taken will also be 15 min., 8 min. and 17 min. i.e. a total of 40 min.

    Hence E.

18. In the given expression the value of the second bracket i.e. 3x - 6 is zero since x = 2.

    Hence zero multiplied by any other expression or number is ZERO.

    Hence C.

19. It is only possible for 3 bananas to be eaten by 3 monkeys in 3 minutes, if each monkey takes 3 minutes to eat one banana.

    Hence even if there are 7 bananas for 7 monkeys (meaning one for each) then each monkey will take 3 minutes only and hence all 7 monkeys will also take 3 minutes as they eat the bananas simultaneously.

    Hence C.

20. Let radius of each of the two smaller circles be r and that of the larger circle be R.
    Given R = 2r
    Area of shaded part
    

    = Twice the area of one smaller circle
    = 2 (p r²)

    Area of unshaded part
    

    = Area of big circle - twice area of smaller circles
    = p R² - 2pr²
    = p(2r) ² - 2pr²
    = 4pr² - 2pr²
    = 2pr²
    
    \

    Hence C.
