  4. D.

    MP, TN

Show answer & explanation

Correct answer: A

Concept

When every compared quantity is multiplied by the same non-zero percentage, their ratio remains the ratio of the original quantities because the common factor cancels.

For a sector receiving p% in every state, sector investment = total investment × p/100; compare a pair by forming this ratio and simplifying.

Application

  1. The Defence share is 25.6% for every state, so the common factor 25.6/100 cancels from each pairwise ratio.

  2. For Rajasthan and Tamil Nadu, the Defence-investment ratio is (3120 × 25.6/100) : (1380 × 25.6/100) = 3120 : 1380.

  3. Divide both terms by 60: 3120 : 1380 = 52 : 23.

Cross-check

Direct calculation gives ₹798.72 crore and ₹353.28 crore; dividing both by 15.36 again gives 52 : 23.

Result

The required pair is Rajasthan and Tamil Nadu.
