Solution
Let the amount invested in schemes A, B and C in Rs. respectively be $2x , 3x$ and $4x$
Amount after 1 year in scheme :
A = $\frac{120}{100} \times 2x = 2.4x$
B = $\frac{116}{100} \times 3x = 3.48x$
C = $\frac{115}{100} \times 4x = 4.6x$
=> Required ratio = 2.4 : 3.48 : 4.6
= 60 : 87 : 115
