Number of candidates from city D = 2.27 lakhs

Ratio of pass : fail = 1: 3

So, number of fail = $$ \frac{3}{3+1}*2.27$$ = 1.7 lakhs

Number of candidates from city A = 1.25 lakhs

Ratio of pass : fail = 7 : 3

So, number of fail = $$ \frac{3}{3+7}*1.25$$ = 37,500

Ratio = 1,70,000 : 37,500. The closest ratio among the answers is (c)

Total candidates appearing from C = 1.08 lakhs

Total candidates appearing from D = 3.14 lakhs

So, the required percentage = 100* 1.08 / 3.14 = 34.39%

Number of candidates appearing from F = 2.73 lakhs

Ratio of Pass: Fail = 7:5

Number of pass = $$ \frac{7}{7+5}$$*2.73 = 1.59 lakhs

Total number of candidates from all the cities = 1.25 + 3.14 + 1.08 + 2.27 + 1.85+ 2.73 = 12.32 lakhs

The required percentage = 100 * 1.59/12.32 = 12.91%

Number of candidates failing = Candidates appearing * Fail side of the ratio/ total ratio

This is the highest for D. The value for D is 2.27 * 3/(3+1) = 1.7 lakhs

Number of candidates passing from E = 1.85 * 3/(3+2) = 1.11 lakhs

Let expenditure of both be e, income of a is p and b is q, as per the graph,we have

35=(p-e)/e*100 So P=( 35e/100)+e, similarly q=(40e/100)+e, solve for p/q, we obtain 135/140 Or 27/28.

Expenditure = (profit / profit %) * 100 (Since, profit = inc - exp)

=> exp = (1,50,000/40)*100 = 3,75,000

It comes as the average of 40,45,40,30,30,45 We get 230/6, Hence, E

Let expenditures of a,b be a,b we have,

50=(i-a)/a*100, 30=(i-b)/b*100 We have,

a=(2/3)*i, b=10*i/13 we get a/b as 13/15

Without individual values of either income or expenditure, We can perform the necessary calculations only when either of the 2 values is given. so, we cannot generate profit percentage. Hence, D
