Let the required number be x.

Let the required number be x. Given that, when multiplied by 7, it gives 7x, and x increases by 78.

Let the required number be x. Given that, when multiplied by 7, it gives 7x, and x increases by 78. According to the question we can write as

Let the required number be x. Given that, when multiplied by 7, it gives 7x, and x increases by 78. According to the question we can write as 7x = x + 78 Transposing x to LHS, we get ⇒

Let the required number be x. Given that, when multiplied by 7, it gives 7x, and x increases by 78. According to the question we can write as 7x = x + 78 Transposing x to LHS, we get ⇒ 7x – x = 78 ⇒

Let the required number be x. Given that, when multiplied by 7, it gives 7x, and x increases by 78. According to the question we can write as 7x = x + 78 Transposing x to LHS, we get ⇒ 7x – x = 78 ⇒ 6x = 78 Dividing both sides by 6 we get ⇒

Let the required number be x. Given that, when multiplied by 7, it gives 7x, and x increases by 78. According to the question we can write as 7x = x + 78 Transposing x to LHS, we get ⇒ 7x – x = 78 ⇒ 6x = 78 Dividing both sides by 6 we get ⇒ 6x/6 = 78/6 ⇒ x =13

Let the required number be x. Given that, when multiplied by 7, it gives 7x, and x increases by 78. According to the question we can write as 7x = x + 78 Transposing x to LHS, we get ⇒ 7x – x = 78 ⇒ 6x = 78 Dividing both sides by 6 we get ⇒ 6x/6 = 78/6 ⇒ x =13 Thus, the required number is x = 13.
