in a 2 digit number , digit in the tens place is four times the digit in the ones place and the sum of the digit is 10. find the number​

Answer»

Answer:

28

Step-by-step explanation:

LET the digit at tens place be x

and the digit at ones place be y

According to question,

y = 4x-------- ( i )

also,

x + y = 10

x + 4x = 10 (from eq.1)

5x = 10

x = 10/5

x = 2

y = 4 × 2 = 8

So,the number = 10 × 2 + 8

= 28 (ANS).
