Question

5) In two digit number, the digit in the tenth place is twice of the digit at unit
place. If digits are reversed the new number is 36 less than the given
number. Find the number​

Answer 1

Answer:

48 or 84

Step-by-step explanation:

let the digit at unit place = x

then digit at tenth place = y

y = 2x ------1

then 10y+ x = nimber

if reversed then number = 10x+ y

after reversing, 10x + y = 10y + x - 36

therefore 9x - 9y = -36

x - y = - 4-------2

using 1 & 2

x - 2x = -4

x = 4

y = 8

therefore number = 48 or 84...
