After 4 months Sujoy joined their business with an amount 20% more than that of Samarth after 2 more months Shimona took out 25% of her investment.

Sujoy invested 9000 more than Samarth and the difference between the profit earned by them is Rs.2000. Correct Answer If the data in statement I alone is sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.

Using statement I

The investment of Samarth and Shimona is in ratio 5 ∶ 4

⇒ Let the investment of Samarth and Shimona be 5x and 4x respectively

Sujoy invested 20% more than that invested by Samarth 

⇒ Investment of Sujoy = (120/100) × 5x = 6x

∴ Profit weightage of Samarth = 5x × 12 = 60x

Profit weightage of Shimona = 4x × 6 + (4x × 75/100) × 6  = 24x + 18x = 42x

Profit weightage of Sujoy = (5x × 120/100) × 8 = 48x

Ratio of profit = 60x ∶ 42x ∶ 48x

⇒ Ratio = 10 ∶ 7 ∶ 8

Total profit = Rs.25,000 

∴ Amount earned by Shimona = (7/25) × 25,000 = Rs.7000

Statement I alone is sufficient to answer the question

 

Using statement II

Samarth invested Rs.9000 more than that of Shimona

⇒ Let the amount invested by Shimona be x

Then, the amount invested by Samarth = x + 7000 

Amount invested by Sujoy = x + 16000 

The difference between the profit earned by them is Rs.2000

Statement II alone is not sufficient to answer the question 

∴ The data in statement I alone is sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
