Answer:I1:I2=50:113
Step-by-step explanation:
for 1st year
A=20000(1+20/100)^1
A=24000
for 2nd year
P=24000
A=24000(1+20/2×100)^2×1
we have multiplied by w because it compounded semi annually

Step-by-step explanation
- Principal is rupees 20,000
- rate is 20 percent per annum
- time is one year
- compound interest is calculated half yearly.
- C.I = P(1+R%) DIVIDED BY 100
- 20000×11÷10×11÷10 = 24200
- INTEREST= 24200-24000
- 4200
- COMPOUNDED ANNUALLY
- C.I =P(1+R%) ÷100
- 20O00×6÷5×6÷5
- 27800
- INTEREST IS 27800-20000
- 7800
- TOTAL INTERST AFTER 2 YEARS IS 7800+4200 =12000
