|
Answer» Let us assume, x and y are the two digits of a two-digit number.Therefore, the two-digit number = 10x + y and the reversed number = 10y + x Given:x + y = 9 ---------1 Also given:10x + y - 9 = 10y + x9x - 9y = 9x - y = 1 -----------2 Adding equation 1 and equation 22x = 10x = 5 Therefore, y = 9 - x = 9 - 5 = 4 Therefore, the two digit number = 10x + y = 10*5 + 4 = 54 Thank you |

two number differ by 40 when each number is increased by 8, the bigger number becomes tries the lesser number if no is x, other number be 40-x ? |
|
Answer» Let bigger number = x Smaller number = 40 - x If each number is increased by 8 The new numbers are , Bigger number = x + 8 Smaller number = 40 - x + 8 = 48 - x According to the problem given , x + 8 = 3 ( 48 - x ) x + 8 = 144 - 3x x + 3x = 144 - 8 4x = 136 x = 136/4 x = 34 Therefore , The bigger number = x = 34 Smaller number = 40 - x = 40 - 34 = 6 I hope this helps you. absolutely correct.... |
