The correct Answer is:
To determine who has the correct answer among Seema, Anees, Asha, and Tessy, we need to evaluate each expression step by step. ### Step 1: Evaluate Seema's Expression **Expression:** \( 4 \times 1 + 8 \div 2 \) 1. **Calculate \( 8 \div 2 \)**: \[ 8 \div 2 = 4 \] 2. **Now substitute back into the expression**: \[ 4 \times 1 + 4 \] 3. **Calculate \( 4 \times 1 \)**: \[ 4 \times 1 = 4 \] 4. **Now add the results**: \[ 4 + 4 = 8 \] **Seema's answer is correct: \( 8 = 8 \)**. ### Step 2: Evaluate Anees's Expression **Expression:** \( 6 + 4 \div 2 - 1 \) 1. **Calculate \( 4 \div 2 \)**: \[ 4 \div 2 = 2 \] 2. **Now substitute back into the expression**: \[ 6 + 2 - 1 \] 3. **Calculate \( 6 + 2 \)**: \[ 6 + 2 = 8 \] 4. **Now subtract 1**: \[ 8 - 1 = 7 \] **Anees's answer is incorrect: \( 7 \neq 4 \)**. ### Step 3: Evaluate Asha's Expression **Expression:** \( 9 + 3 \times 2 - 4 \div 2 \) 1. **Calculate \( 4 \div 2 \)**: \[ 4 \div 2 = 2 \] 2. **Now substitute back into the expression**: \[ 9 + 3 \times 2 - 2 \] 3. **Calculate \( 3 \times 2 \)**: \[ 3 \times 2 = 6 \] 4. **Now substitute back**: \[ 9 + 6 - 2 \] 5. **Calculate \( 9 + 6 \)**: \[ 9 + 6 = 15 \] 6. **Now subtract 2**: \[ 15 - 2 = 13 \] **Asha's answer is incorrect: \( 13 \neq 10 \)**. ### Step 4: Evaluate Tessy's Expression **Expression:** \( 27 \div 3 - 2 \times 3 \) 1. **Calculate \( 27 \div 3 \)**: \[ 27 \div 3 = 9 \] 2. **Now substitute back into the expression**: \[ 9 - 2 \times 3 \] 3. **Calculate \( 2 \times 3 \)**: \[ 2 \times 3 = 6 \] 4. **Now substitute back**: \[ 9 - 6 \] 5. **Now subtract**: \[ 9 - 6 = 3 \] **Tessy's answer is incorrect: \( 3 \neq 21 \)**. ### Conclusion The only correct answer is from Seema: **Seema's Expression: \( 4 \times 1 + 8 \div 2 = 8 \) is correct.**
