Discussion :: Banker's Discount - General Questions (Q.No.10)

10. 

The banker's gain on a certain sum due 1 1 years hence is 3 of the banker's
2 25

discount. The rate percent is:

[A].
5 1 %
5
[B].
9 1 %
11
[C].
8 1 %
8
[D].
6 1 %
6

Answer: Option B

Explanation:

Let, B.D = Re. 1.

Then, B.G. = Re. 3 .
25

T.D. = (B.D. - B.G.) = Re. 1 - 3 = Re. 22 .
25 25

Sum = 1 x (22/25) = Rs. 22 .
1-(22/25) 3

S.I. on Rs. 22 for 1 1 years is Re. 1.
3 2

Rate = 100 x 1 %
= 100 = 9 1 %.
11 11
22 x 3
3 2

What is the B.D and B.G?

King said: (Dec 15, 2011)  
B.D means banker discount and B.G means banker gain

How is possible for Re. 1.

Ruchi said: (Sep 21, 2013)  
Given T = 3/2.

B.G = 3/25 of B.D.

R = ?

Now, T.D = B.D - B.G.

(True discount = Banker's discount - Banker's gain).

T.D = B.D - 3/25B.D.

T.D = 22/25 B.D........(1).

Again TD = BD*100/(100+RT).

From equ(1).

22/25 BD = BD*100 /[100+(3/2)R].

22/25 = 100/[100+(3/2)R].

R = 100/11.

Real = 9 1/11.

Dear, Can you explain in brief?

Suresh said: (Nov 7, 2015)  
(1*22/25)/(1-22/25)? How it comes for 3/25?

Karthika said: (Jun 27, 2016)  
@Suresh

1*22/25 = 55/25.
1 - 22/25 = 3/25.
= 22/3.

Anyone. Please tell me a common procedure to find the rate percent.

Swetha said: (Aug 25, 2016)  
Please explain the answer simply and clearly.

T.D = B.G X 100/T X R,
Assume B.D = Rs 1,
Then T.D = B.D - B.G.

How can we assume BD = 1?

Syed said: (Feb 14, 2018)  
Please explain the Answer Clearly.
