Answer 2

✪ Given ✪

• A number consists of hwo digits whose sum is 9.
• If 27 is subtracted from the number its digits are reversed.

✪ To find ✪

The number.

✪ Solution ✪

Let the ones digit be x.

So, the tens digit = (9-x).

According to condition,

{10(9-x)+x} - 27 = {10x+(9-x)}

→ {10(9-x)+x} - {10x+(9-x)} = 27

→ (90-10x+x) - (10x+9-x) = 27

→ (90-9x) - (9x+9) = 27

→ -18x+81 = 27

→ -18x = 27-81

→ -18x = -54

→ x = -54/-18

→ x = 3

✪ Hence ✪

☞ Ones digit = x = 3.

☞ Tens digit = (9-x) = (9-3) = 6.

✪ Therefore ✪

The number is 63.
