Correct answer is: None of these
Explanation:
Let the amount invested in schemes A, B aand C in Rs. respectively be 2x, 3x and 4x
Amount after 1 year in scheme :
\(A = \frac{120}{100} \times 2x = 2.4 x\)
\(B = \frac{116}{100} \times 3x = 3.48x\)
\(C = \frac{115}{100}\times 4x =4.6x\)
\(\implies \text{Required ratio =} 2.4: 3.48:4.6\)
\(= 60:87:115\)
