Answer:

B

Given that , compound interest ( C.I. ) = ₹ 615 , simple interest ( S.I. ) = ₹ 600 , Time = 2 years

∴ C.I. – S.I. = 615 – 600 = ₹ 15

S.I. for 1 year =  

600

= ₹ 300

2

∴  S.I. for 1 year on ₹ 300 = ₹ 15

∴  Rate =  

15 × 100

= 5%

300 × 1

As we know that ,

∴  

PRT

= 600

100

⇒  P ×  

5 × 2

= 600

100

⇒  P = 600 × 10 = ₹ 6000
