Here , 4 months = 1 years 3 & there4; Banker deducts ₹3 × 1 = ₹1 from a bill of ₹100 3
Banker 's discount = ₹1
So, the banker pays ₹(100 - 1) = ₹99.
Amount = ₹ 99
So, the bill-holder loses ₹1.
So, for investment ₹1 should be interest on ₹99 for 4 months.∴ Rate of interest = Banker 's discount × 100 % Amount × Time ∴ Rate of interest = 1 × 100 = 100 = 3 1 % 99 × 4/12 33 33 Correct Option: C

Here , Selling Price of motor- cycle = ₹35000
Cost Price of motor- cycle = ₹32500
∴ Gain = Selling Price - Cost Price
Gain = ₹35000 - ₹32500
Gain = ₹2500∴ Gain % = Gain × 100 % Cost Price Correct Option: B
Here , Selling Price of motor- cycle = ₹35000
Cost Price of motor- cycle = ₹32500
∴ Gain = Selling Price - Cost Price
Gain = ₹35000 - ₹32500
Gain = ₹2500∴ Gain % = Gain × 100 % Cost Price ∴ Gain % = 2500 × 100 % 32500 = 100 % = 7 9 % 13 7

Here , Amount = ₹17850 , Rate = 5% ,
S.I. on ₹17850 at 5% is ₹357.∴ Time = S.I. x 100 Amount x Rate Time = 100 × 357 = 2 Year = 146 Days 17850 × 5 5
So, the bill is 146 days prior to May 24, the legally due date.
Sum of the number of Days ( May + April + March + Feb. + Jan. + Dec. ) = 24 + 30 + 31 + 28 + 31 + 2 = 146 days So, the bill was discounted on Dec 29, 1990.Correct Option: A
