(a) ₹ 1872
Explanation:
Present value= ₹ 10000
Interest rate= 10% per annum
Time=3 years
To find the amount we have the formula,
Amount (A) = P (1+(R/100))n
Where P is present value, r is rate of interest, n is time in years.
Now substituting the values in above formula we get,
∴ A = 10000 (1 + 12/100)1 [1 + (12/2 )/100]
⇒ A = 10000 (1+12/100)1(1+6/100)
⇒ A = 10000 (112/100) (106/100)
⇒ A = 1 × 112 × 106
⇒ A = ₹ 11872
∴ Compound interest = A – P
= 11872 – 10000= ₹ 1872
