Ankush and Vishal started a business by investing Rs. 3000 and Rs. 5000 respectively. At the end of the year they earned a profit of Rs. 1600. Find the share of Vishal in the total profit.

- A.
Rs. 600

- B.
Rs. 1200

- C.
Rs. 800

- D.
Rs. 1000

Answer: Option D

**Explanation** :

Since both of them invest for the same amount of time, profit will be divided in the ratio of their investments.

Ratio of investment for Ankush and Vishal = 3000 : 5000 = 3 : 5

Hence, share of Vishal = 5/8 × 1600 = 1000.

Hence, option (d).

Ankush and Vishal started a business by investing Rs. 3000 each. Ankush left the business after 7 months and withdrew his entire investment while Vishal stayed in the business till the end. At the end of the year they earned a profit of Rs. 3800. Find the share of Ankush in the total profit.

- A.
Rs. 1200

- B.
Rs. 1400

- C.
Rs. 2400

- D.
Rs. 2000

Answer: Option B

**Explanation** :

Since both of them invested the same amount, profit will be divided in the ratio of their time they were invested for.

Ratio of investment for Ankush and Vishal = 7 months : 12 months = 7 : 12

Hence, share of Ankush = 7/19 × 3800 = 1400.

Hence, option (b).

Ankush and Vishal started a business by investing Rs. 3000 and Rs. 5000 respectively. Ankush left the business after 7 months and withdrew his entire investment while Vishal stayed in the business till the end. At the end of the year they earned a profit of Rs. 5400. Find the difference between the profit received by the two.

- A.
Rs. 1200

- B.
Rs. 1600

- C.
Rs. 2600

- D.
None of these

Answer: Option C

**Explanation** :

We know, Profit ∝ Investment × Time

Ratio of profit for Ankush and Vishal = 3000 × 7 : 5000 × 12 months = 7 : 20

Hence, share of Ankush = 7/27 × 5400 = 1400.

Share of Vishal = 5400 – 1400 = 4000.

Hence, the difference = 4000 – 1400 = 2600.

Hence, option (c).

Three partners shared the profit in a business in the ratio 5 : 8 : 7. They had partnered for 14 months, 7 months and 8 months respectively. What was the ratio of their investments?

- A.
5 : 8 : 7

- B.
38 : 21 : 28

- C.
20 : 64 : 49

- D.
None of these

Answer: Option C

**Explanation** :

Let their investments be Rs. x for 14 months, Rs. y for 7 months and Rs. z for 8 months respectively.

We know, Profit ∝ Investment × Time

Hence, ratio of their profit, 5 : 8 : 7 = 14x : 7y : 8z.

Now, 14x/7y = 5/8 ⇒ y = 16/5 x

And, 14x/8z = 5/7 ⇒ z = 49/20 x

∴ x ∶ y ∶ z = x ∶ 16/5 x ∶ 49/20 x = 20 ∶ 64 ∶ 49

Alternately,

We know, ratio of their profit, 5 : 8 : 7 = 14x : 7y : 8z.

⇒ x : y : z = $\frac{5}{14}:\frac{8}{7}:\frac{7}{8}$= $\frac{56\times 5}{14}:\frac{56\times 8}{7}:\frac{56\times 7}{8}$ = 20 : 64 : 49

Hence, option (c).

Ankush starts business with Rs. 10,500 and after 5 months, Vishal joins with Ankush as his partner. After a year, the profit is divided in the ratio 2 : 3. What is B's contribution in the capital?

- A.
Rs. 22,500

- B.
Rs. 27,000

- C.
Rs. 25,500

- D.
Rs. 24,000

Answer: Option B

**Explanation** :

Let B's capital be Rs. x.

We know, Profit ∝ Investment × Time

Then, 2/3 = (10,500 × 12) / (x × 7)

⇒ x = $\frac{10,500\times 12\times 3}{7\times 2}$

⇒ x = 27,000.

Hence, option (b).

A and B invest in a business in the ratio 3 : 2. If 5% of the total profit goes to charity and A's share is Rs. 1710, the total profit is:

- A.
Rs. 2850

- B.
Rs. 3000

- C.
Rs. 3075

- D.
Rs. 3152

Answer: Option B

**Explanation** :

Let the total profit be Rs. 100P.

After paying to charity, A's share = Rs. 95P × $\frac{3}{5}$ = Rs. 57P

Given, A's share is Rs. 57P = 1710

⇒ P = 1710/57 = 30

Total profit = 100 × 30 = 3000

Hence, option (b).

A, B and C jointly engaged themselves in a business venture. It was agreed that A would invest Rs. 13,000 for 6 months, B, Rs. 16,800 for 5 months and C, Rs. 20,000 for 3 months. A wants to be the working member for which, he was to receive 5% of the profits. The profit earned was Rs. 14,800. Calculate the share of B in the profit.

- A.
Rs. 3800

- B.
Rs. 5320

- C.
Rs. 5600

- D.
Rs. 5680

Answer: Option B

**Explanation** :

For managing, A received = 5% of Rs. 14,800 = Rs. 740.

Balance = Rs. (14,800 - 740) = Rs. 14,060.

Ratio of their investments = (13,000 × 6) : (16,800 × 5) : (20000 × 3) = 78000 : 84000 : 60000 = 13 : 14 : 10

∴ B's share = Rs. (14,060 × 14/37) = Rs. 5320.

Hence, option (b).

A, B and C enter into a partnership in the ratio $\frac{7}{2}:\frac{4}{3}:\frac{6}{5}$. After 4 months, A increases his share 50%. If the total profit at the end of one year be Rs. 43,200, then B's share in the profit is:

- A.
Rs. 4200

- B.
Rs. 4800

- C.
Rs. 7200

- D.
Rs. 8000

Answer: Option D

**Explanation** :

Ratio of initial investments = $\frac{7}{2}:\frac{4}{3}:\frac{6}{5}$ = 105 : 40 : 36.

Let the initial investments be 105x, 40x and 36x.

∴ Ratio of profits of A : B : C = $(105x\times 4+\frac{150}{100}\times 105x\times 8)$ : $(40x\times 12)$ : $(36x\times 12)$ = 1680x : 480x : 432x = 35 : 10 : 9.

Hence, B's share = Rs. (43,200 × 10/54) = Rs. 8000.

A, B, C subscribe Rs. 1,00,000 for a business. A subscribes Rs. 8,000 more than B and B Rs. 10,000 more than C. Out of a total profit of Rs. 1,05,000, A receives:

- A.
Rs. 25,200

- B.
Rs. 35,700

- C.
Rs. 40,800

- D.
Rs. 44,100

Answer: Option D

**Explanation** :

Let C’s investment = x.

Then, B = x + 10,000 and A = x + 10,000 + 8,000 = x + 18,000.

So, x + x + 10,000 + x + 18,000 = 1,00,000

∴ 3x = 72,000

∴ x = 24,000

A : B : C = 42000 : 34000 : 24000 = 21 : 17 : 12.

∴ A's share = Rs.(1,05,000 × 21/50) = Rs. 44,100.

Hence, option (d).

Ankush and Vishal entered into partnership with capitals in the ratio 4 : 5. After 3 months, Ankush withdrew 1/4th of his capital and Vishal withdrew 1/5th of his capital. The gain at the end of 10 months was Rs. 1520. Ankush's share in this profit is:

- A.
Rs. 760

- B.
Rs. 720

- C.
Rs. 660

- D.
Rs. 860

Answer: Option C

**Explanation** :

Let initial investment of Ankush = 4x and that of Vishal = 3x.

Ratio of profits of Ankush and Vishal = $[4x\times 3+(4x-\frac{1}{4}\times 4x)\times 7]$ : $[5x\times 3+(5x-\frac{1}{5}\times 5x)\times 7]$

= (12x + 21x) : (15x + 28x) = 33x : 43x = 33 : 43.

Ankush's share = Rs. (1520 × 33/76) = Rs. 660.

Hence, option (c).

A began business with Rs. 1,250 and is joined afterwards by B with Rs. 3,750. When did B join if the profits at the end of the year are divided equally.

- A.
After 6 months

- B.
After 8 months

- C.
After 4 months

- D.
After 7 months

Answer: Option B

**Explanation** :

Let B joined for x months.

∴ P_{A }: P_{B }= I_{A }× T_{A} ∶ I_{B }× T_{B}

⇒ 1/1 = (1250 × 12)/(3750 × x)

⇒ x = 4

Hence, he joined after 12 - 4 = 8 months.

Nirmal and Kapil starting a business investing Rs. 9,000 and Rs. 12,000 respectively. After 6 months, Kapil withdrew half of his investment. If after a year, the total profit was Rs. 4,600 what was Kapil’s share in it?

- A.
Rs. 2000

- B.
Rs. 2600

- C.
Rs. 1900

- D.
Rs. 2300

Answer: Option D

**Explanation** :

Nirmal’s investment for 12 months = 9,000

Kapil average investment for 12 months = (12000 × 6 + 6000 × 6)/12 = 9,000

∴ Ratio of their profit = Ratio of their investment

⇒ Profit of Nirmal : Profit of Kapil = 9000 : 9000 = 1 : 1

Hence, Kapil’s profit = 1/2 × 4600 = 2300.

Hence, option (d).
