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
