Answer:
Explanation:
Let total shirts be x. 
Then, Striped shirts = 1/9x 
Remaining Shirts= 8/9x 
Therefore, Printed Shirts = 5/8 × 8/9x 
= 5/9x 
Remaining Shirts 
or 
Plain Shirts= x - ( 5/9x + 1/9x ) 
= 3/9x 
Acc. to problem, 
Plain Shirts=81 
Therefore, 
3/9x=81 
=> x=81×9/3 
=> x=27×9=243 
Therefore, 
Total Shirts= 243
