Banker's Discount - Arithmetic Aptitude Questions and Answers

Home / Arithmetic Aptitude / Banker's Discount :: Discussion

The banker's gain on a certain sum due 1 $\frac { 1 } { 2 }$ years hence is $\frac { 3} { 25 }$ of the banker's discount. The rate percent is:

5 $\frac { 1 } { 5 }$ %

9 $\frac { 1 } { 11 }$ %

8 $\frac { 1 } { 8 }$ %

6 $\frac { 1 } {6 }$ %

Answer : Option B

Explanation :

Let, B.D = Re. 1.

Then, B.G. = Re . $\frac { 3 } { 25 }$

T.D. = (B.D. - B.G.) = Re [1- $\frac { 3 } { 25 }$ ]= Re. $\frac { 22 } { 25 }$

Sum = [ $[\frac { 1 *(22/25) } { 1-(22/25) }]$ =Rs. $\frac { 22 } { 3 }$

S.I. on Rs. $\frac { 22 } { 3 }$ for 1 $\frac { 1 } { 2 }$ yeras is Re .1.

Rate = $[\frac { 100*1 } { 22/3*3/2 } ]$ % = $\frac { 100 } { 11 }$ = 9 $\frac { 1} { 11 }$ %
