Profit share of Rekha and Tarun = 33(1/3):66(2/3) = 1:2

(x – 2000)/(x + 1000) = 1/2

x + 1000 = 2x – 4000

x = 5000

Investment of Tarun = 5000 + 1000 = Rs.6000

Downstream speed = 120/6 = 20 kmph

Upstream speed = 45/4.5 = 10 kmph

Speed of stream = (20 – 10)/2 = 5 kmph

SI = P * R * N/100

CI = P * (1 + R/100)n – P

(x – 2000) * 72/100 = x * 18*3/100

4x – 8000 = 3x

x = 8000

CI received by Kanna = 6000 * (1 + 10/100)3 – 6000

= Rs.1986

Banu = 24 years

Esai = 24 – 8 = 16 years

Prabha = 5/4 * 24 = 30 years

Dina = 30 – 20 = 10 years

Renu = 3/1 * 10 = 30 years

Required average = (24 + 16 + 30 + 10 + 30)/5

= 22 years

Expenditure of Anil = 4 * 4000 = 16000

Expenditure of Nila = 5 * 4000 = 20000

(5x – 16000)/(6x – 20000) = 1/1

6x – 20000 = 5x – 16000

x = 4000

Income of Anil = 5 * 4000 = 20000

Expenditure of Amuthan = 80/100 * 12500 = 10000

Savings of Amuthan = 12500 – 10000 = 2500

Savings of Bharathi = 3/5 * 2500 = 1500

Income of Bharathi = 4/1 * 1500 = Rs.6000

The interest is half yearly = 20/2 = 10%

Half yearly time = 4 years

x * (1 + 10/100)4 – x = 1392.3

0.4641x = 1392.3

x = 3000

Let Weight of the manager = x

30 * 60 + x = 62 * 31

x = 122 kg

P                           Q

Ratio of Profit               12000 x 5     :        18000 x 3

10           :                9 Let the speed of the boat in still water and that of the stream be 6X kmph and X kmph respectively.

According to question, X = 7

Upstream speed = 6X – X = 5X = 5 * 7 = 35 kmph
