X and Z invest capital in the ratio of 2 : 1 while X and Y invest capital in the ratio of 3 : 2. If their annual profit is Rs. 157300 then what is Y share ?
Discuss
Answer & Solution
Answer: Option A
Solution:
Given
X : Z = 2 : 1
X : Y = 3 : 2

X : Z = 2 : 1 (multiply with 3)
X : Y = 3 : 2 (multiply with 2)

i.e X : Z = 6 : 3
X : Y = 6 : 4

∴ X : Y : Z = 6 : 4 : 3
According to the question
(6 + 4 + 3) units = Rs.157300
13 units = Rs.157300
1 unit = Rs.12100
4 units = Rs.12100 × 4 = Rs. 48400
∴ Share of Y = Rs. 48400

A and B start a business with investments of Rs. 5000 and Rs. 4500 respectively. After 4 months, A takes out half of his capital. After two more months B takes out one-third of his capital while C joins them with a capital of Rs. 7000. At the end of a year, they earn a profit of Rs. 5080. Find the share of each member in the profit ?
Discuss
Answer & Solution
Answer: Option B
Solution:
A : B : C
(5000 × 4 + 2500 × 8) : (4500 × 6 + 3000 × 6) : (7000 × 6)
= 40000 : 45000 : 42000
= 40 : 45 : 42
$$\eqalign{ & \therefore {\text{A's share}} \cr & = {\text{Rs}}{\text{.}}\left( {5080 \times \frac{{40}}{{127}}} \right) \cr & = {\text{Rs}}{\text{.}}\,{\text{1600}} \cr & \therefore {\text{B's share}} \cr & = {\text{Rs}}{\text{.}}\left( {5080 \times \frac{{45}}{{127}}} \right) \cr & = {\text{Rs}}{\text{.}}\,{\text{1800}} \cr & \therefore {\text{C's share}} \cr & = {\text{Rs}}{\text{.}}\left( {5080 \times \frac{{42}}{{127}}} \right) \cr & = {\text{Rs}}{\text{.}}\,{\text{1680}} \cr} $$

A and B started a business investing amounts in the ratio of 2 : 3. If A has invested an additional amount of Rs. 10000, their ratio of investment would have been 3 : 2. The amount invested by A was ?
Discuss
Answer & Solution
Answer: Option A
Solution:
Initial ratio of investments by A and B = 2 : 3
Let their respective investments are 2x and 3x
According to the question,
If A added Rs. 10000 to his investment
Then the new ratio = 3 : 2
$$\eqalign{ & \Rightarrow \frac{{2x + 10000}}{{3x}} = \frac{3}{2} \cr & \Rightarrow 4x + 20000 = 9x \cr & \Rightarrow 5x = 20000 \cr & \Rightarrow x = 4000 \cr} $$
Original investment by A = 2 × 4000 = Rs. 8000

A, B and C started a business investing amounts in the ratio of 5 : 6 : 8 respectively. After one year, C withdrew 50% of the amount and A invested an additional amount of 60% of the original amount invested by him. In what ratio, the profit earned at the end of 2 years should be distributed among A, B and C respectively ?
Discuss
Answer & Solution
Answer: Option C
Solution:
Let the initial investments of A, B and C be Rs. 5x, Rs. 6x and Rs. 8x respectively
Then, A : B : C
[5x × 12 + (160% of 5x) × 12] : (6x × 24) : (8x × 12 + 4x × 12)
= 156x : 144x : 144x
= 13 : 12 : 12
