Question

Find the time in whichRs.500 will become Rs.750 at the rate of 12% per annum.​

Answer 1

Answer:

Step-by-step explanation:

Amount=Principal×rate×years of number÷100

750=500×12%×Years÷100

Years= 750×100÷500×12

Years taken= 12.5 yrs

Answer 2

Answer:

so apply

500(1+12%)^n = 750

(1+.12)^n = 3/2

1.12^n = 3/2

take log both side

log(1.12^n) = log (3/2)

n*log1.12 = log(3/2)

so, n= 3.57 nearly 3.6
