Question

c. The ones digit of a two-digit number is thrice the tens digit. If the digits are
interchanged, the new number becomes 10 more than twice the old number. Find the
number.​

Answer 1

Answer:

26

Step-by-step explanation:

let tens digit no= X

so once digit no= 3X

so number formed 10×X+3X= 10X+3X= 13X

if digit interchanged then number = 10×3X+X= 30X+X= 31X

A.T.Q

2(13X)+10 = 31X

26X+10 = 31X

10 = 31X-26X

10 = 5X

10÷5 = X

2 =X

Number formed is 10×X+3X

= 10×2+3×2

= 20+6

= 26
