E Correct answer
Explanation

To find Rajesh's present age, we need all three statements. From I and III: 5 years ago Shreya:Preeti = 2:3, let S=2x, P=3x. Currently S=2x+5, P=3x+5. Since Shreya is 5 years younger than Preeti now, 2x+5 = (3x+5) - 5, giving x=5. So Shreya is 15, Preeti is 20 currently. From II: 3 years ago Rajesh:Shreya = 3:4, so (R-3):(15-3) = 3:4, giving R-3 = 9, so R=12. All three statements are necessary.
