Let the sum borrowed be x.
Then, (x*2*6)/100 + (x*9*3)/100 + (x*14*4)/100 = 11400
(3x/25 + 27x/100 + 14x / 25) = 11400
95x/100 = 11400
x = (11400*100)/95 = 12000.
Hence , sum borrowed = Rs.12,000.

Answer:
Let the sum borrowed be x.
Then, (x*2*6)/100 + (x*9*3)/100 + (x*14*4)/100 = 11400
(3x/25 + 27x/100 + 14x / 25) = 11400
95x/100 = 11400
x = (11400*100)/95 = 12000.
Hence , sum borrowed = Rs.12,000.
