Question

find a number such that if 5 15 and 35 added to it the product of first and third result may be equal to the square of the second​

Answer 1

Answer:

Ans = 5

Step-by-step explanation:

Let x be added to 5,15 and 35, such that we have (x + 5) (x + 35) = (x + 15)2

⇒ x2 + 40x + 175 = x2 + 225 +30x

⇒ 10x = 50

⇒ x = 5

Hence, 5 is the required number.
