Expert Answer
Let Anita had x number of marbles initially . 
 
Hence number of marbles with Ritu = (26-x) 
 
After loosing 3 marbles, number of marbles with Anita = ( x-3)
 
After loosing 3 marbles, number of marbles with Ritu = ( 26- x-3) = ( 23 - x )
 
If product of their marbels is 91 , then we have
 
( x-3) (23-x) = 91
 
23x - 69 - x2 + 3x = 91 
 
x2 -26x +160 = 0
