2)And – b)54%
The overall % increase in the sale of all the 5 companies together
= 5/20×80 + 4/20×50 + 3/20×60 + 2/20×30 + 6/20×40.
= 20+10+9+3+12 = 54%
3) The overall % increase in the sale of company C and D together in 55% in the year 2004, find the ratio of sale of company C and D in year 2004?
a)80:13 b)55:23 c)13:65 d)180 :130

3) Ans -a)80:13
55% increase in the sale of company C and D together is weighted mean of 60% and 30% .
C D
60% 30%
55%
25 5
5 : 1 =ratio of sale in year 2003
Now, sale of company C in 2004/ sale of company D in 2004
= (5 x 160/100)/ 1 x 130/100= 80/13
4)If the ration of sale of company C,D and E in year 2004 5 : 3 : 4 then find the overall % increase in the sale of company C,D and E together from 2003 to 2004(approx) ?
a)41% b)56% c)46% d)48%
Click to View Answer
4) Ans- c)46%
Ratio of sale in year 200 =5 : 3 : 4
ratio of sale in 2003 C = 5/160×100 = 3.12
D= 3/130 x 100= 2.3
E= 4/140 x 100= 2.8
Total C+D+E = 8.2
the overall increase= (12- 8.2)/8.2 x 100 ≈ 46%.
5) The overall % increase in the sale of companies B and C together is 57% and that of companies C and D together is 37% in year 2004 .find the ratio of sale of companies C,D and E in year 2003?

Percentage of people commuting by road= 55%
And,
Percentage of people commuting by De-luxe buses = 27.8%
Percentage of people commuting by air rout = 18.8%
Percentage of people commuting by Jet airways =16%
hence , the required difference = 71142/100 [55 x 27.8 – 18.8 x 16 ]
= 71142/100[12.298] ≈ 8738.
7)what is the percentage change from percentage increase in the number of person going by De-luxe train from mumbai to pune from 1991 to 1992 to the percentage increase in those going by indian air lines from pune to Delhi ?

% increase in the number of person going De-luxe train from Mumbai to pune from 1991- 1992
[ (501-417)/417]*100= 20.14%
No. of person going by Indian airlines from pune to delhi in 1991=

OR
Just calculate = total no. in 1993 =50209
in 1994 =63587
