Question

Poornima took a loan of Rs 100000 from bank at the rate of 10 % compound interest immediately she lent the whole amount to her friend at 10% compounded half yearly how much profit will she make at the end of 2 years​

Answer 1

Answer:

Rs 20,000/_

Step-by-step explanation:

Poornima took a loan of=Rs 1,00,000

Rate of interest per year=10℅ = (1,00,000×10)÷100= 10,000

Taking compounded from friend per half year(6 months)=10% =10,000

2 years compounded= 10,000 ×4= 40,000

bank's interest for 2 years= 20,000

poornima profit=40,000-20,000=Rs 20,000

Answer 2

Answer:

profit= Rs 550.625

Step-by-step explanation:

Given,  

P = Rs 100000

t = 2years

r= 10%

we know,  

Profit = P(1+r/(2*100))^2t - P(1+r/100)^t

= 100000(1+10/2000^4 - 100000(1+10/100)^2

= 121550.625-121000

= Rs 550.625 is the profit

(subtract half-yearly value and yearly value)

You can also solve them separately and then subtract.
