|
Answer» Answer: Let the number be N Let X be the bigger number Then , X-Y=15 ; Y : X = 3:4(X is bigger) So, Y/3 = X/4 let,Y/3 = X/4 = K Then , Y= 3K,X = 4K X-Y = 15 ,SO , 4K-3K=15 Hence , K = 15. Y = 3*15 =45 ;X = 4 *15 = 60 N = X + Y = 105 hence , The number is 105 ; Its parts are 60,45. Read more on Brainly.in - brainly.in/question/1699526#readmore |

The digits of a 2 digit number differs by 3 If the digits are interchanged and the resulting number is added to the original number get 142. What will be the orginal number? |
|
Answer» Step-by-step EXPLANATION: the digits of two digit number DIFFER by , there are two possibilities. One the unit digit be x and tens digit be x + 3 , and two that tens digit is x and unit digit is x + 3 . In first case, if unit digit be x and tens digit is x + 3 , then number is ( x + 3 ) + x = 11 x + 30 and on interchanging numbers, it will BECOME 10 x + x + 3 = 11 x + 3 . As sum of numbers is 143 , we have 11 x + 30 + 11 x + 3 = 143 or 22 x = 110 and x = 5 . and number is 58 . |
