Answer:
Members of Singing group will buy minimum 135 number of balcony tickets.
Step-by-step explanation:
Given:
Minimum of tickets will be bought =250
Let number of lawn tickets be 'l'.
Also Let number of balcony tickets be 'b'
Now given
The group buys 20 fewer lawn tickets than balcony tickets.
Framing in equation form we get;

Now The Sum of Number of balcony tickets and Number of lawn tickets should be greater than or equal to Minimum of tickets will be bought by the group.
Framing in equation form we get;

Now substituting the value of 'l' in above equation we get;

Now we know the value of b which is 135 we will substitute in equation
to find the value of l we get;

Hence Members of singing group will buy minimum 135 number of balcony tickets.
