Question

In a two-digit number, the digit in the tens place is four times the digit in the units place. If
the sum of the digits is 10, find the number.
​

Answer 1

Step-by-step explanation:

let tens place digit be x. and unit place be y

x=4y

x-4y=0........ 1

x+y=10.........2

subtract 2 from 1

thus y =2

putting y=2 in 2

x+2=10

x=10-2

x=8

the no is 10x+y=10*8+2

=80+2

=82
