→ Hey Mate,

→ Given Question:-

→ A two digit number is such that the product of its digits is 8. When 54 subtracted from the number, the digits are reversed. Find the number.

→ To find:-

→ Find the number?

→ Solution:-

→ Let digit at ones = x

→ Let digit at Tens = y

→ Now , = 10 y + x

→ x + y = 8 [ ∵ Equation 1 ]

→ 10 y + x -54  =  10 x + y

→ 10 y - y + x - 10x = 54

→ 9y - 9x = 54

→ Now , solve equation 1 and equation 2

→ x + y = 8

→ -x + y = 6

→ y = 7

→ 2y = 14

→ x = 1

→ The Number is 71.
