Answer 1

Answer:

$\huge\mathfrak\pink{Answer:}$

Rate (R) = 8% p.a.

Period (T) = 5 Years

Interest (T) = ₹ 12000

(i) ∴ Sum = (I × 100)/(R × T)

= ₹ ((12000 × 100)/(8 × 5)) = ₹ 30000

(ii) Rate (R) = 10% p.a.

Time (T) = 2 Years

Principal (P) = ₹30000

Interest for the first year = PRT/100

= ₹ ((30000 × 10 ×1)/100) = ₹3000

∴ Amount after one year = ₹30000 + 3000

₹ 33000

Principal for the second year = ₹ 33000

Interest for the second year = (33000 × 10 ×1)/100

= ₹ 3300

∴ Compound interest for two years

= ₹3000 + 3300 = ₹ 6300
