Answers:
Q.1 sol: - (4)  Day/दिन

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

 Efficiency of 2men, 1 women and 3 child = 2*4 + 6 + 3* 5 = 29
Work in 10 days = 29 * 10 = 290 work
Remaining work = 360 – 290 = 70 work
Work increased so new work = 130 + 70 = 200 work
New efficiency of men, women and boy = 6, 9 and 10 respectively.
Now in one day work done by all of them = 6*2 + 9 + 3*10 = 51 work
Work to be completed in =  days =  

Q.2 Q.:-solution:- (4) 7 : 6
Efficiency of Men for construction, electrification and painting = 6 + 2 + 5 = 13
Efficiency of women for construction, electrification and painting = 3 + 8 + 4 = 15
Efficiency of men  for painting, designing from wood work = 14
Efficiency of  boy for painting, designing from wood work = 10
Required ratio = (13 + 15) : (14 + 10)
= 28 : 24
= 7 : 6

Q.3 solution:- After solving value of x = 3, and y = 2 
Number of days for wood =   = 24
Number of days for electrification = 
Required ratio = 24:  
= 23: 12

Q.(4) Solution:-  Number of days required by a man to complete the construction work =  = 60 day
Number of days required by a boy to complete the designing work =  = 80 days
Required percentage = 

Q.5 sol:- No. of days taken by boy to complete the construction work =  = 30 days/दिन
लडको द्वारा निर्माण कार्य समाप्त करने में लागा समय  =  = 30 दिन
No. of days taken by boy to complete the electrification work =  = 32 days
लडको द्वारा विद्युतीकरण  कार्य समाप्त करने में लागा समय  =  = 32 दिन
No. of days taken by boy to complete the painting work =  = 80 days
लडको द्वारा पेंटिंग कार्य समाप्त करने में लागा समय  =  = 80 दिन
No. of days taken by boy to complete the designing work =  = 80 days
लडको द्वारा डिजाइनिंग कार्य समाप्त करने में लागा समय  =  = 80 दिन
No. of days taken by boy to complete the wood work =  = 72 days
लडको द्वारा लकड़ी का  कार्य समाप्त करने में लागा समय  =  = 72दिन 
Required average =  =  =  days 

Q.6) Solution:- Total arrangements possible = (9!) / 2     -    -------- (1)
E between H and N = (7!  2) / 2    ---------- (2)
P(E between H and N) = eq (2) / eq (1)
= 1/ 36
हल :- कुल व्यस्था   =. (9!) / 2     -    -------- (1)
कुल व्यस्था जिसमे E H और N के मध्य हो = (7!  2) / 2    ---------- (2)
कुल प्रयुक्ता जिसमे E H और N के मध्य हो= eq (2) / eq (1)
= 1/ 36

Q.7)Solution:- data inadequate /अपर्याप्त आकंडे 

Q.8 SOLUTION:- 
LOGIC:-  (÷ 2) - 1, (÷ 2) - 2, (÷ 2) - 3, (÷ 2) - 4, (÷ 2) – 5

Q.9 SOLUTION:- 
LOGIC:- + 1, + 3, + 5, + 7, + 9 

Q.10: SOLUTION:- Logic:-
