When a number is divided by 7 and the answer is 3 remainder 4 what is the number?

To solve this problem, we can set up the equation n = 7q + 4, where n is the unknown number, q is the quotient, and 4 is the remainder. Since the problem states that when n is divided by 7, the quotient is 3, we can substitute q = 3 into the equation to get n = 7(3) + 4 = 21 + 4 = 25. Therefore, the number in question is 25.
