The correct Answer is:
To solve the problem, we will set up equations based on the statements made by Mohit and Rohit. Let: - \( M \) = number of oranges Mohit has - \( R \) = number of oranges Rohit has ### Step 1: Create the first equation based on Mohit's statement Mohit says, "If you give me 10 of your oranges, I will have twice the number of oranges left with you." If Rohit gives Mohit 10 oranges: - Mohit's new count = \( M + 10 \) - Rohit's new count = \( R - 10 \) According to Mohit's statement: \[ M + 10 = 2(R - 10) \] ### Step 2: Simplify the first equation Expanding the equation: \[ M + 10 = 2R - 20 \] Rearranging gives: \[ M = 2R - 30 \quad \text{(Equation 1)} \] ### Step 3: Create the second equation based on Rohit's statement Rohit replies, "If you give me 10 of your oranges, I will have the same number of oranges as left with you." If Mohit gives Rohit 10 oranges: - Mohit's new count = \( M - 10 \) - Rohit's new count = \( R + 10 \) According to Rohit's statement: \[ R + 10 = M - 10 \] ### Step 4: Simplify the second equation Rearranging gives: \[ M = R + 20 \quad \text{(Equation 2)} \] ### Step 5: Solve the equations simultaneously Now we have two equations: 1. \( M = 2R - 30 \) 2. \( M = R + 20 \) We can set these equations equal to each other: \[ 2R - 30 = R + 20 \] ### Step 6: Solve for \( R \) Subtract \( R \) from both sides: \[ 2R - R - 30 = 20 \] This simplifies to: \[ R - 30 = 20 \] Adding 30 to both sides gives: \[ R = 50 \] ### Step 7: Find \( M \) using \( R \) Now substitute \( R = 50 \) back into Equation 2: \[ M = R + 20 = 50 + 20 = 70 \] ### Final Answer Thus, the number of oranges with Mohit and Rohit are: - Mohit: \( 70 \) - Rohit: \( 50 \)
