Answer» Answer: 2 ans = Let the SMALLER number =x. greater number =3x. The NEW number after ADDING =3. To the smaller number =x+3. Equation: 3x-(x+3)=31. 3x-(x+3)=31. 3x+-x-3=31. 3x-x-3=31. 2x-3=31. 2x=31+3. 2x=34. x=34/2 =17. Smaller number (x) =17 . Greater number (3x) =3x17. =51 is the answer. 3 ans = Let the ones digit =x. Sum of digit =14. Tens digit =(14-x). The ORIGINAL number =10(14-x)+x x 1. =140-10+x. 140-9x. New number after reversing the digit =10xx+(1x14-x). 10x+14-x. 9x+14. Equation =9x+14+18=140-9x. 9x+14+18=140-9x. 9x+32=140-9x. 9x+9x=140-32. 19x=108. x=108/8. One's digit =6. Ten's digit =14-x. 14-6. 8. original number =86. |
