14. 30 minutes

15. i) 10

ii) 16

16. a) 4.73 kg

b) 8.004 kg

17. 40.5 km

Step-by-step explanation:

14.

total distance to be covered = distance to be travelled -distance already travelled =

-205-5=210 m

time = distance/speed

time= 210/7=30minutes

15.

i) if neha got 10 correct answers and scored 30 , it means ,

she should have scored 50 marks for 10 X 5 =50

it means that she got 20marks deducted

so no. of incorrect answer she probably got is ,

50-30/2=20/2=10

So total no. of ques is 20

ii) if he got 4 correct answers , he should have scored 20 marks but he got -12

sono. of incorrect ans he got is 20-(-12)/2=20+12/2=32/2=16

Hope it helps ...
