Question

Find compound interest on rupees 20000 at 10per cent per annum for
$2 \times \frac{1}{4}$
years

Answer 1

Principal =₹ 20,000
Rate = 10%
Time 2½ years
In compound interest :
P(1+r/100)²
20,000(1+10/100)²
20,000*110/100*110/100
= ₹24,200
SI = p*r*t/100
SI = 20,000*10*1/2*100
SI = ₹ 1,000
Total = 24,200+1,000 = ₹25,200
CI = A-P = 25,200-20,000 = ₹ 5,200

So,hope it may help you
