Answer 1

Answer:

1. R = I× 100/P× T

R= 100×100/100×5

R = 20%

Step-by-step explanation:

2.Ramesh loss 3840 ₹

1st Ramesh lent out 8000 for 5 years at 15% per annum

Interest = 8000×5×15/100

Interest = 6000₹

so, Ramesh gain 6000₹ as interest

2nd Ramesh borrowed 6000 for 3 years at 12% per annum

Interest = 6000×3×12/100

INTEREST = 2160₹

SO Ramesh give 2160 as interest

Obviously Ramesh Gain( 6000-2160 )=3840₹
