Mr Amin borrowed some money from Mr Vishwas. The rate of interest for first two years is 8% p.a., for the next three years is 11 % p.a. and for the period beyond 5 years 14% p.a. Mr Vishwas got an amount of 10920 as an interest at the end of eight years. Then what amount was borrowed by Mr Amin ?  Choose one:
A) 12000  B) 15000  C) 1400  D) Data inadequate  E) None of these
Let ‘x’ be the amount borrowed by Mr Amin.   ∴ x×2×8/100+x×3×11/100+x×3×14/100=10920   or, 91⁄100x = 10920 or x = 10920×100/91=12000   12000nswer 12000
