e) Sri

After 2 years, Aโs age = Present age of B

Cโs present age = 22

4 years ago, C = 3*B

18 = 3*B

Bโs age 4 years ago = (18/3) = 6

Bโs present age = 10

After 2 years, Aโs age = 10

Aโs present age = 8 years

n(S) = 52C2

n(E) = 4C2

P(E) = n(E)/n(S) = 4C2/ 52C2

= > (4*3)/(52*51)

= > 1/221

Let the cost price of door and TV set be x and y respectively,

X + y = 40000 —ร  (1)

(20/100)*x + (30/100)*y = 10500

2x + 3y = 105000 —ร  (2)

By solving the equation (1) and (2), we get,

X = 15000, y = 25000

The selling price of TV set = 25000*(130/100) = Rs. 32500

(Or)

Percentage of total profit = (10500/40000)*100 = 26.25 %

= > 375: 625

= > 3: 5

8โs = 40000

1โs = 5000

Cost price of TV set = 5โs = Rs. 25000

Selling price of TV set = 25000*(130/100) = Rs. 32500

The ratio of Salary of A and B = 80: 100 = 4: 5

The ratio of Salary of B and C = 120: 100 = 6: 5

The ratio of Salary of A, B and C = 24: 30: 25

54โs = 32400

1โs = 600

The salary of C = 25โs = Rs. 15000

1. I = Pnr/100

(1/9)*P = P*r2/100 [n = r]

(1/9) = r2/100

r2 = 100/9 = 10/3 = 3 1/3 %

Rate of interest = 3 1/3 %

Direction (6-10) :

The total annual profit of Karthi and Rahul in the year 2015 and 2017 together

= > 3.4 + 4 + 5 + 5.3 = 17.7 lakhs

The total annual profit of Ravi and Sri in the year 2013 and 2016 together

= > 3.25 + 4 + 4 + 5.75 = 17 lakhs

Required % = (17.7/17)*100 = 104 %

The average annual profit of Santhosh in all the given years together

= > (3.5 + 3.8 + 4.4 + 4.6 + 5.25)/5 = 21.55/5

= > 4.31 lakhs

The total annual profit of Ravi in the year 2013, 2015 and 2017 together

= > 3.25 + 5.6 + 5.2 = 14.05 lakhs

The total annual profit of Rahul in the year 2014, 2015 and 2016 together

= > 3.5 + 4 + 4.6 = 12.1 lakhs

Required ratio = 14.05 : 12.1 = 1405 : 1210

= > 281 : 242

The total annual profits of the given business man together in the year 2015

= > 5.6 + 3.4 + 4 + 4.4 + 5.25 = 22.65 lakhs

= > 5.2 + 5 + 5.3 + 5.25 + 6.5 = 27.25 lakhs

Required difference = 27.25 โ 22.65 = 4.6 lakhs

Ravi = > 3.25 + 4.5 + 5.6 + 4 + 5.2 = 22.55 lakhs

Karthi = > 2.8 + 2.6 + 3.4 + 3.75 + 5 = 17.55 lakhs

Rahul = > 4.2 + 3.5 + 4 + 4.6 + 5.3 = 21.6 lakhs
