Answer

1. Answer : 4


 Explanation : Required Percentage =100-5050×100= 100% 


 


2. Answer : 4 


Explanation : The average production of P = 60+90+50+100+805= 76 


The average production of Q =50+70+70+80+1005  = 74 


The average production of R = 70+80+90+70+705 = 76


Maximum average production = P and R both


  


3. Answer : 2 


Explanation : The percentage rise in 2010 =70-5050×100 = 40% 


The percentage rise in 2011 = 70-7070×100= 0% 


The percentage rise in 2012 = 80-7070×100= 14.28% 


The percentage rise in 2013 =100-8080×100 =25% 


 


4. Answer : 2


Explanation : The percentage of production of Company R to production of Company Q

in 2012 = 7080×100= 87.5  


in 2013 = 70100×100= 70 


 


 


5. Answer : 1


Explanation : Average production of company P during the years 2011 to 2013 =50+100+803 = 2303

In a triangle ABC, angle 'a' is the smallest one & A+7B = 112. Find the range of value 'c' ?

A) 138 to 164 B) 125 to 147
C) 148 to 158 D) 152 to 164
 
Answer & Explanation Answer: D) 152 to 164

Explanation:

A+7B=112

it is clear that A = 14, then it becomes A>=B, but A is smallest angle) given
so, range of A is 0.0001 to 13.9999 ( I am taking upto 4 decimal places)
so, range of B becomes 14 to 16 ( after rounding off to 4 decimal places)
so, range of C becomes 152 to 164 ( after rounding off to 4 decimal places)
