Option 3 : Rs. 3300

**Given:**

Amount invested by A = Rs. 24000

Amount invested by B = Rs. 30000

Amount invested by C = Rs. 36000

After 6 months B took out Rs. 5000

and after 4 months C took out Rs. 6000

After 1 year total profit = Rs. 10020

**Formula used:**

Profit = Invested amount × Time

**Calculation:**

B's remaining amount after 6 months = Rs. (30,000 - 5000)

⇒ Rs. 25000

C's remaining amount after 4 months = Rs. (36,000 - 6000)

⇒ Rs. 30,000

Now Ratio of profit A, B and C

⇒ (24000 × 12) : {(30000 × 6) + (25000 × 6)} : {(36000 × 4) + (30000 × 8)}

⇒ 288000 : (180000 + 150000) : (144000 + 240000)

⇒ 288000 : 330000 : 384000

⇒ 48 : 55 : 64

Ratio of profit A, B and C = 48 : 55 : 64

Total profit = (48 + 55 + 64) units

⇒ 167 units

According to the question,

167 units = Rs. 10020

⇒ 1 unit = Rs. 60

⇒ 55 units = Rs. 3300

B's share in profit = 55 units

⇒ Rs. 3300

**∴ The share of B in the profit will be Rs. 3300.**
