Arushi was to multiply a number by 2.4 but instead multiplied by 4.2. If the product she obtained was 65.1. Let the number that was supposed to be multiplied by 2.4 be x. According to the question, x × 4.2 = 65.1 x = 15.5 Now, the actual number = 15.5 × 2.4 = 37.2 ∴ The correct product that she should have got is 37.2.
