ANSWERS WITH EXPLANATION
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
