Data Sufficiency — compute Vinod's salary from a ratio Given: Vinod : Javed salary ratio = 4 : 3. Statements: I. Javed's salary is 75% of Vinod's salary. II. Javed's salary is Rs 4500. Choose the correct sufficiency option.

Difficulty: Easy

I alone is sufficient while II alone is not sufficient
II alone is sufficient while I alone is not sufficient
Either I or II is sufficient
Neither I nor II is sufficient

Correct Answer: II alone is sufficient while I alone is not sufficient

Explanation:

Use the ratio
Given 4:3 (Vinod:Javed). From II: Javed = ₹4500 ⇒ Vinod = 4500 × (4/3) = ₹6000.

Check I
“Javed is 75% of Vinod” is equivalent to the given ratio (3/4), but gives no absolute amount ⇒ insufficient.

Answer
II alone is sufficient while I alone is not sufficient.
