Answer 1

Answer:

Correct Option: D

Step-by-step explanation:

As per the given question ,

BD for 3 years = Rs. 1116

BD for 4 years = 1116 × 4 = Rs. 1488

3

TD for 4 years = Rs. 1200

F = Banker's Discount × True Discount

Banker's Discount - True Discount

F = 1488 × 1200

( 1488 – 1200 )

F = 1488 × 1200

288

F = 1488 × 1200

24

F = 62 × 100

F = Rs. 6200

⇒ Rs.1488 is the simple interest on Rs. 6200 for 4 years

⇒ 1488 = 6200 × 4 × R

100

⇒ R = 1488 × 100

6200 × 4

⇒ R = 372 × 100

6200

⇒ R = 372 = 6%

62

Hence , Rate percent is 6% .
