Question

7. In a two digit number, digit in units place is twice the digit in tens place. If 27 is added to it,
digits are reversed. Find the number.​

Answer 1

Answer:

Let number on tens place be = x

Let the number on ones place be =2x

Place value H T O

X (2x)

10*x+2x

= 10x+2x

= 12x

Reversing digit

= H T. O

(2x). X

10(2x) +x

20x+x

21x

Related to 27

12x + 27 = 21x

27 = 21x - 12x

27 = 9x

27÷9 = x

3 = x

First number = 12x

Number = 12*3 = 36

Second number = 21x

Number = 21*3 = 63

Checking

27 added to first number = second number

27+ 36 = 63
