(2) Find a number which when added to its half gives 42.
(3) A number when multiplied by 4 exceeds itself by 36. Find the number ?

Dear Student,


Let the number be xwhen number is multiplied by 4 i.e. 4x it exceeds itself i.e x by 36Therefore we get the following equation4x=x+364x-x=363x=36x=363x=12Hence the number is 12

LET THE NUMBER BE X 
=4*x - 36 
=4X - 36
= WE CAN'T SOLVE THE BOTH TERMS BECAUSE THEY ARE UNLIKE TERMS.

The number is 12, because 12 x 4 = 48 and the difference between them is 36.
Therefore 12 is the answer.
