Answers
Q.1 solution:-
After solving value of x = 3, and y = 2
Type of work | Eff. Of MEN | Eff. Of WOMEN | Eff. Of BOY | Total contracts | Combined efficiency of all of them (Men + Women + boy) |
| Construction | 2 | 3 | 4 | 120 | 9 |
| Electrification | 6 | 8 | 9 | 288 | 23 |
| Painting | 5 | 4 | 2 | 160 | 11 |
| Designing | 5 | 6 | 3 | 240 | 14 |
| Wood work | 4 | 6 | 5 | 360 | 15 |
Number of days for wood = 
= 24
= 24
Number of days for electrification = 
Required ratio = 24: 
= 23: 12
Q.2 solution:-
SOLUTION:- 
= 85%APPROX (लगभग)
Q.3 Solution:-
Number of days required to complete the construction work previously = 
After applying more workers = 
Required answer = 
= 
=
Q.4 solution:-
Number of days required by men to do construction work:- 
Number of days required by men to do electrification work:- 
Number of days required by men to do painting work:- 
Number of days required by men to do designing work:- 
Number of days required by men to do wood work:- 
Required average/अभीष्ट औसत = 
Q.5 Solution:-
New efficiency of men = 3
New efficiency of women = 9
New efficiency of boy = 10
Now number of days required to complete the work = 
= 
दिन
= दिन
The questions given below contain two statements giving certain data. You have to decide whether the data given in the statements are sufficient for answering the question? Mark answer-
नीचे दिए गए प्रश्नों में दो कथनों के माध्यम से कुछ जानकारियां दी गई हैं आपको यह निर्णय करना है कि क्या कथनो में दी गई जानकारी उत्तर देने के लिए पर्याप्त हैं? उत्तर दीजिए-
Q.6:- solution:-
I. Area =
lb = 40
II. BD2 = DC2 + BC2
l2+ b2= 400
both the statement are sufficient.
Q.7 solution:-
I. m=1
II. m = 7
either I or II is sufficient
Q.8: solution:-
I. n+P+W = 48
average = 
II. w>P+n
Only I statement is sufficient.
Q.9 solution:-
I. R–S = S–M? S = 
II. R+M = 98
Together not sufficient.
Q:-10:-solution
(3) If statement I and II together are not sufficient. यदि I व II दोनों अपर्याप्त हैं।
