Question

In a two-digit number the units digit is four times the tens digit and the sum of the digits is 10,
Find the number

Answer 1

Answer:

28

Step-by-step explanation:

Let the ten's place be x and unit's place be y.

According to the question,

y = 4x      ...(1)

x + y = 10        

By (1), x + 4x = 10

5x = 10

x = 2          ...(2)

In (1), y = 4(2)      ...[by (2)]

y = 8

So the number is 28.

Hope this helps you!!!!

Answer 2

Answer:

28

explanation= let the tens digit be X

and the unit digit be 4x

sum of the digits is 10.

so, x+4x =10

5x= 10

X= 10/ 5

x= 2.

so,we got the value of x.

now, put the value in equation

tens digit=x=2

unit digit= 4x= 4×2= 8

so the two digit number= 28.

Hope it helps...
