Question

if the unit digit is 5 and the tens digit is 2 then the number is​

Answer 1

Answer:

25

Step-by-step explanation:

As 2 is the tens digit and 5 is the ones digit, the answer becomes 25

Answer 2

Answer:

Let the digit in the units place be x

Hence the digit in the tens place is (x+5)

The original number =10(x+5)+x=11x+50

Number formed by reversing the digits =10x+(x+5)=11x+5

Given that:- (11x+50)+(11x+5)=99

⇒22x+55=99

⇒22x=99−55=44

⇒x=2

∴ Original number =11x+50=11(2)+50=72

Hence the original number is 72.

Hence the correct answer is 72.
