QUESTION is incomplete. QUESTION : Five-ninth of a number is equal to twenty five per cent of second number. Second number is equal to one-fourth of third number. The value of third number is 2960. What is 30% of first number?
(a) 88.8   (b) 99.9 (c) 66.6    (d) cannot be determined   (e) None of these

SOLUTION :

Let x, y, and z be the three numbers.
y = z/4 (GIVEN)5x/9 = 25%of (y)5x/9 =( 25/100) × z/4
5x/9 = 25z/400    
5x × 400 = 9 × 25z
2000x = 225z           (GIVEN, z = 2960)
x =( 225 × 2960)/2000  x = 333   

30% of first number = 30% of x= (30 /100) × 333 = 999/10 = 99.9
Hence, 30% of first number is 99.9.
