Question

Value of a two digits number when reversed is 6 less than twice its value when unreversed.if the difference of its digits is 2 find the number

Answer 1

Answer:

24

Step-by-step explanation:

ab is the number

1. b-a=2 => b=a+2

2. ba=2ab-6

• ab=10a+b
• ba=10b+a

Solving based on above given:

• 10b+a=2(10a+b)-6
• 8b+6=19a

Replacing b with a+2

• 8(a+2)+6=19a
• 11a=22

• a=2 and b=a+2=4

So the number is 24

Proof:

42=24*2-6
