100+ Bankers Discount Questions and Answers for Bank Exams - 1

Ans: C

Given B.D. for $$1{1}/{2}$$ years = Rs. 837.

∴ B.D. for 2 years = Rs. 837 × $${2}/{3}$$ × 2 = Rs. 1116

T.D. for 2 years = 900.

Sum = $${B.D. × T.D.} / {B.D. - T.D.}$$ =$${1116 × 900}/{1116 - 900}$$ = $${1116 × 900}/{216}$$ = Rs. 4650.

∴ Rs. 1116 is S.I. on Rs. 4650

∴ Rate = $$({1116 × 100}/{4650 × 2})$$ = 12%.

Ans: A

B.D. for $${3}/{2}$$ years = Rs.558

B.D. for 2 years = Rs. $$(558 × {2}/{3} × 2)$$ = Rs. 744.

T.D. for 2 years = Rs. 600.

∴ Sum = $${B.D. × T.D.} / {B.D. - T.D.}$$ = Rs. $$({744 × 600} / {144})$$ = Rs. 3100.

Thus, Rs. 744 is S.I. on Rs. 3100 for 2 years.

Ans: C

Let, B.D. = Rs. 1. Then, B.G. = Rs. $${3}/{25}$$.

∴ T.D. = (B.D. – B.G.) = Rs. $$(1 – {3}/{25})$$ = Rs. $${22}/{25}$$.

Sum = $$({1 × 22/25} /{1 - 22/25})$$ = $${22}/{3}$$.

S.I. on Rs. $${22}/{3}$$ for $$1{1}/{2}$$ years is Rs. 1.

∴ Rate = $$({100 × 1} /{22/3 × 3/2})$$% = $$9{1}/{9}$$%.

Ans: B

B.G. = $${(T.D.)^2}/{P.W.}$$ = Rs. $${(130)^2}/{1300}$$ = Rs. 13.

∴ B.D. = T.D. + B.G. = 130 + 13 = Rs. 143.

∴ Banker’s discount = Rs. 143.

∴ Banker’s gain = Rs. 13.
