1. Ans-e
Y= 15,7
No relation
2. Ans-e
No relations
3. Ans-b
4. Ans-e
 X=25, -8
Y=25, 6
No relation
5. Ans-a
Manhours spent in sketching= 430
Option a- 100+430=530
Option b-430
Option c-280+150=430
Option d-280+430=710
6. Ans-c
Total work = (
%=330/1140  *100= 28.94 %=30%
7. Ans-c
Total manhours spent  international= 330
Option a- 80+100=180
Option b -400
Option c-280
Option d-400/2=200
Option e-100
8. Ans-a
Total working hours= 1140
Now it is given 100 hours is
equal to 1140 man hours.
Hence 50 hours will be equal to
(1140/100)x50= 570 manhours
Option a shows manhours nearest
to it=430+100=530
9. Ans-b
Total national work=
50% national work is carried
international =405
Distribution of
Efforts distributed to
crafts=43/114 X 405= 153 man hours
national craftwork= 0.5×280=140
Proportion of craft carried out
national= 140/(140+140+153)   x 100=
32.33=30 %
10. Ans-a
Ratio of distribution of
50 % of 810 or 405 manhours is
carried international.
Then distribution of
international work=
Amount of sketching done=
Amount of craftdone=
Since amount of sketching done is
greater than amount of craft, hence option a is correct.
