Ex 1.2, 8 (Method 1) A student multiplied 7236 by 65 instead of multiplying by 56. By how much was his answer greater than the correct answer? (Hint: Do you need to do both the multiplications?) Wrong multiplication = 7236 × 65 Right multiplication = 7236 × 56 Difference between both answers = 7236 × 65 − 7236 × 56 Taking 7236 common = 7236 × (65 − 56) = 7236 × 9 So, wrong answer was greater than right answer by 65,124. Ex 1.2, 8 (Method 2) A student multiplied 7236 by 65 instead of multiplying by 56. By how much was his answer greater than the correct answer?
