Answer 2

Given:  

2/3rd of a number is 30.  

To Find:  

The value of the number is?  

Solution:  

The given problem can be solved using simple algebra.  

1. The value of 2/3rd of a number is 30.  

2. Let the value of the original number be n,  

=> (2n)/3 = 30, (Solve for value of n)  

=> 2x = 3x30,  

=> 2x = 90,  

=> x = 90/2,

=> x = (2x45)/2,  

=> x = 45.  

3. The value of the number is 45.

Therefore, the value of the number is 45.
