Given two varieties of sugar sugar S1 and sugar S2. Sugar S1 costs \$6 per kilogram and sugar S2 costs \$9 per kilogram. Sugar S1 is mixed with Sugar S2 and a new variety of Sugar S3 is formed.

Also given if 20 kilograms of Sugar S3 consists of A kilogram of Sugar S1 and B kilogram of Sugar S2
⇒ A + B = 20

Considering statement 1:
A > 9
As no information is given regarding B and the Cost of Sugar S3 , it is not possible to determine whether A > B or not. A and B both may be 10 kg each (i.e. A is not greater than B) or A = 11 and B = 9 (i.e. A > B).

Since we are not getting a definite answer from above statement , statement 1 itself is not sufficient to provide the answer.

Considering statement 2:
The cost of 20 kilogram of Sugar S3 is more than \$150.
⇒ 6A + 9B > 150

Putting B = 20 − A gives:
6A + 9(20 − A) > 150
⇒ A < 10
Hence, B will be greater than 10 (as sum of A and B is 20)
⇒ A is definitely not greater than B.

Since we are getting a definite answer from above statement, statement 2 itself is sufficient to provide the answer.

I think, I deserve a kudus LOL
