A) 1200and 1300
B) 1350 and 1150
C) 1225 and 275
D) none of these
Correct Answer: A
Solution :
Suppose he borrowed Rs. x at 12% and Rs. (2500 ? x) 14% per annum. Then, S.I. on Rs. x \[1000\times \frac{(100-30)}{100}\times \frac{(100-40)}{100}\] And S.I. on \[(2500-x)\] \[\because \] \[\frac{25}{100}\times x=20,000\] \[x=80,000\] Therefore, he borrowed 1200 at 12% and 1300 at 14%.
