Answer 1

$<i>$
Let, number be x.

Divide the assumed number by 2 to make its half.

i.e. ( x / 2 )

Now,

A/q

Assumed number + Half of the assumed number = 66

x + ( x / 2 ) = 66

L.C.M. of 1 and 2 = 2

•°•

( 2x + x ) / 2 = 66

3x / 2 = 66

x = ( 66 × 2 ) / 3

x = 44

Hence, the number is 44.

Answer 2

$<b><i>$Let the required number be x.

A/q,

x + x/2 = 66

=> 2x + x/2 = 66

=> 3x/2 = 66

=> 3x = 66 × 2

=> x = 132/3

=> x = 44

Hence, the required number is 44.
