Correct Answer - Option 1 : A
Given:
Ritesh, Gaurav and Jugnu invest in the ratio 2 : 5 : 7.
The ratio of their investment return percentage is 5 : 3 : 2.
Gaurav earns more than Rs 150 from Ritesh.
Calculation:
Let the Ritesh, Gaurav and Jugnu invest be 2x, 5x, 7x.
The ratio of their investment return percentage is 5 : 3 : 2.
The profit of Ritesh = 2x × 5/100 = 1/10x
The profit of Gaurav = 5x × 3/100 = 3/20x
The profit of Jugni = 7x × 2/100 = 7/50x
The ratio of Ritesh, Gaurav and Jugnu profit = 1/10x : 3/20x : 7/50x
The ratio of Ritesh, Gaurav and Jugnu profit =10 : 15 : 14
According to the question:
Gaurav earns more than Rs 150 from Ritesh.
Then, 15 - 10 = 150
⇒ 5 = 150
⇒ 1 = 30
The total income = 30 × 39 = 1170
∴ The total income is Rs.1170.
