Answer

Orginal no. is 60.

Step-by-step explanation:

Let 2/3 of the orginal no. be 2/3x. Forming the equation, we get, x- 2/3x =20 ( 2/3x is less than x by 20 means that their differnce is 20) Taking x common from the L.H.S, x(1-2/3) = 20. Subtracting (1 - 2/3 )on the L.H.S, x ( 1/3 ) =20. x = 20 / (1/3) x = 60.
