We have 225>135 So, we apply the division lemma to 225 and 135 to obtain 225=135*1+90 r is not equal to 0 135=90*1+45 r is not equal to 0 90=45*2+0. r=0 The divisor at this stage is45. Therefore the HCF of 135 and 225 is 45.

Let us assume √5 is rational number which can be written in the form p/q there for √5=p/q (where p and q are co-prime integer and q is not equal to 0) √5q=p --equation first squareing both side 5q²=p² here five divides p² Therefore 5 also divides p let p = 5C putting value of p is equation first equation √5q= 5C squaring both side 5q² = 25c² q²=5c² q²/5 =c² Here 5 divides q² Therefore 5 also divides q Here we can see 5 divides both integer p and q but it contradicts that p and q are co prime integer this contradiction arising due to our wrong assumption therefore √ 5 is irrational number.

Let the digit in the unit's place be x and the digit in the ten's place be y.
Then, Number =10y + x
According to the given condition, we have
The ten's digit is three times the unit's digit.
y = 3x ..............(i)
Number obtained by reversing the digits =10x + y
If the number is decreased by 54, the digits are reversed.
{tex}\therefore{/tex} Number - 54 =Number obtained by reversing the digits
⇒ 10y + x -54 =10x + y
⇒ x - 10x + 10y - y = 54
⇒ - 9x + 9y = 54
⇒ 9x - 9y =-54
 ⇒ x - y =-6 ............(ii)
Putting y = 3x in equation (ii), we get
⇒ x - y = 6
⇒ x - 3x = -6
⇒ - 2x = -6
 ⇒ x = 3
Putting x = 3 in y = 3x, we get y =9
 The number = 10y + x = 10{tex}\times{/tex} 9 + 3 = 90 + 3 = 93
Hence the given two digit number is 93.
