Here total experditure of both companies are given while their individual expenditures are needed to determine their incomes, Since their total income of the two companies can not be determined by the given datas
In 2004, expenditure of Company 'A' = Rs. 75 lakh
Since, income of the company 'A' in 2004 = 75 + 25/100 x 75 = Rs. 93.75 lakhs
Now, expenditure of the 'A' in 2005 = Rs. 93.75 lakhs
Since, their income = 93.75 + 50/100 x 93.75 = Rs. 140.62 lakhs
Hence total income for both the years = 93.75 + 140.62 = Rs. 234.37 lakhs
Expenditure = Income - Profit
As per given graph in question,
Income in 2005 = 1,42,500 Rs.
Profit in 2005 = 50%
Let expenditure of Company A in 2005 = Rs. E; then
E + E x 50/ 100 =142500
? E + E x 1/2 =142500
? (2E + E)/2 =142500
? 3E =142500 x 2
? E =142500 x 2/ 3
? E = 47500 x 2
? E = Rs. 95000
Let expenditure of company B in 2005 = Rs. x; then
I1(Income) = x + 35/100 x = Rs. 27x/20
Since . expenditure of company B in 2006 = 90/100 x Rs. x = Rs. 9x/10.then
I2(Income ) = 9x/10 + 45/100 x 9x/10 = 9x/10 +81x/200 = Rs. 261x/200
Hence, required percentage = 261x/200/27x20 x 100 = 290/3 = 962/3%
Let expenditures of Company B in 2003 and 2004 are Rs. 5x and Rs. 7x respectively; then
their income in 2003, I1= 5x + 40/100 x 5x = Rs. 7x
Also their income in 204, I2 = 7x + 30/100 x 7x = Rs. 91x/10
Hence, the required ratio = 7x : 91x/10 = 10 : 13
Average number of building = number of building across the cities (P + Q + R + S + T )/5
Average number of building = 50 + 175 + 150 + 75 + 175/5 = 625/5 = 125
As we see in the graph the Export graph is higher for 2003 to 2004 years. So we will calculate for this year.
Required percentage for 2004 = (Export in 2004 - Export in 2003) x 100/Export in 2004
Required percentage for 2004 = (600 - 200) x 100/200 = 200%
Required percentage = 950 - 200/200 x 100 = 375%
Required difference = Rs. (600 - 450) crores = Rs. 150 croes
Total export in given years = Rs. (300 + 200 + 600 + 450 + 600 + 800 + 950) crores = Rs. 3900 crores
Required percentage = Export in 2004 x 100/Export in 2005
Required percentage = 600 x 100 /450= 400/3 = 133.33% ? 135%
