ANSWERS WITH EXPLNATION

1.     (5) Difference = 52500 – 47500 = 5000

2.    (1) Required percentage =( 25/35) X 100 = 71.43 %

3.     (5) Required percentage = [( 42.5 – 37.5)/(37.5)]X 100= 13.33 %

4.    (3) Required ratio = (45 – 42.5) : (37.5 – 30) = 1 : 3

5.    (4) Required average = (35000 + 37500 + 42500 + 45000 + 47500 + 52500)/6  =43330 (approx).

6.    (3) Required ratio = 475 : 425 = 19 : 17

7.    (5) Total distance travelled by all trucks = 475 + 350 + 550 + 425 + 525 = 2325 km

Average distance = 2325/5 = 465 km .

8.    (2) Time taken by truck C = 550/55 = 10 hours.

9.    (1) Required percentage =( 475)/ ( 550 + 525) ] X 100 = 44% ( approx)

10.  (4) Speed of truck B = 350/8 = 43.75 km/hr
