Best answer

i. Here P = Rs 2000, R = 5 p.c.p.a. and N = 2 years

= 5 × 441 

∴ A = Rs 2205

I = Amount (A) – Principal (P) 

= 2205 – 2000 

= Rs 205

∴ The amount is Rs 2205 and the compound interest is Rs 205.

ii. Here, P = Rs 5000, R = 8 p.c.p.a. and N = 3 years.

∴ A = Rs 6298.56 

I = Amount (A) – Principal (P) 

= 6298.56 – 5000 

= Rs 1298.56

∴ The amount is Rs 6298.56 and the compound interest is Rs 1298.56.

iii. Here, P = Rs 4000, R = 7.5 p.c.p.a. and N = 2 years

∴ A = Rs 4622.50 

I = Amount (A) – Principal (P) 

= 4622.50 – 4000

= Rs 622.50 

∴The amount is Rs 4622.50 and the compound interest is Rs 622.50.
