Answers :

1) Answer B:

According to the chart:

Investment in business C by

P = 15% of 18000

= Rs 2700

For 3 years

Q = 30% of 18000

= 5400

For 1 year

R = 25% of 18000

= 4500

For 2 years

Required ratio = 2700*3: 5400*1: 4500*2

= 9: 6: 10

2) Answer C:

For business A

Q invested Rs 3600 for 4 years

For business B

Q invested Rs 1800 for 5 years

For business C

Q invested Rs 5400 for 1 years

For business D

Q invested Rs 4500 for 2 years

For business E

Q invested Rs 2700 for 3 years

Ratio of Q’s investment made in all the business

= 16: 10: 6: 10: 9

Hence option.

A and C satisfies.

3) Answer E:

 from previous Question ratio of the investment in all the business by Q

= 16: 10: 6: 10: 9

From option A of the previous Question

Q’s profit in E is

= Rs 1620

The ratio of profit in business E by all 3 individuals

= 1800*5: 2700*3: 3600*4

= 10: 9: 16

Required difference = 16 – 10 = 6

Given 9 = 1620

6 = Rs. 1080

From option C of the previous Question

Q’s profit in E is

= Rs 1710

The ratio of profit in business E by all 3 individuals

= 1800*5: 2700*3: 3600*4

= 10: 9: 16

Required difference = 16 – 10 = 6

Given 9 = 1710

6 = Rs. 1140

4) Answer D:

Investment of R in C is Rs. 4500

from previous Question ratio of the investment in all the business by Q

= 16: 10: 6: 10: 9

The ratio of profit in business E by all 3 individuals

= 1800*5: 2700*3: 3600*4

= 10: 9: 16

Condition1.

Profit earned by R in E

Given 9 = 1620

1 = 180

R in E = 16*180

= 2880

Required % = 4500/2880

= 156%

Condition2.

Profit earned by R in E

Given 9 = 1710

1 = 190

R in E = 16*190

= Rs 3040

Required % = 4500/3040

= 148%

5) Answer C:

Ratio of Profit earned by P in all its business

= 5400*1: 4500*2: 2700*3: 3600*4: 1800*5

= 6: 10: 9: 16: 10

Ratio of profit earned in business D is

= 3600*4: 4500*2: 2700*3

= 16: 10: 9

Given 16+10+9 = 35

35 = 4550

1 = 130

Profit of P in business D

= 130*16

= Rs 2080

Profit of P in business B

16 = 2080

10 = 1300

Hence required Answer is Rs. 1300
