Question

1.Twothirdofanumberis20lessthantheoriginalnumber.Findthe
number.

Answer 1

Step-by-step explanation:

if we think the original number is = x

then, 2/3 rd of that number is = x - 20

2/3 x = x - 20

x - 2/3 x = 20

x/3 = 20

x = 60

therefore the original number is 60

Answer 2

Step-by-step explanation:

Given that: Two third of a number is 20 less than the original number.

To find: That number

Solution: Let the number is x

(2/3)Rd of x is 2x/3

ATQ

$\frac{2x}{3}=x-20$

Put the terms of x at LHS

$\frac{2x}{3}-x=-20\\\\\frac{2x-3x}{3}=-20$

cross multiply

-x= -20×3

-x=-60

x=60

That number is 60.
