Answer» First NUMBER = 15Second number = 25Step-by-step EXPLANATION:Let,First number = 3xSecond number = 5xIf each number is increased by 10 First number = 3x + 10Second number = 5x + 10Also,The ratio between the new NUMBERS so FORMED is 5:7 So,⇒ ⇒ 7 (3x + 10) = 5 ( 5x + 10)⇒ 21x + 70 = 25x + 50⇒ 21x - 25x = 50 - 70⇒ - 4x = - 20⇒ 4x = 20⇒ x = 20 / 4⇒ x = 5________________________★ Value of 3x :⇒ 3 (5)⇒ 15_________________________★ Value of 5x :⇒ 5 (5)⇒ 25Therefore,First number = 15Second number = 25 |
