B. In what time will Rs 10000 will yield a compound interest of Rs 2769​

after 8years

Step-by-step explanation:

Complete question;

In what time will Rs 10000 will yield a compound interest of Rs 2769​ at 3% per annum

Using the compound interest formula;

A =P(1+r)^n

Given

P = Rs10000

A = 10000+2769

A = 12769

rate = 3% = 0.03

Substitute and get the time t

12769 = 10000(1+0.03)^n

12769/10000 = 1.03^n

1.2769 = 1.03^n

log 1.2769 = nlog1.03

n =  log 1.2769/log 1.03

n = 0.1062/0.01283

n = 8.27

Hence the time is approximately after 8years

the answer will be b x² +x-1
