27
2.
Go annually compounded​

Answer 1

Step-by-step explanation:

A=59826,R=21%,T=18 months

A=P×[1+r/100]ⁿ

t=18/12=t=3/2

then,if time will be double then rate will be halved,so,t=3yrs,R=21/2%

and it also a half yearly.

we will put given information

59826=p×[1+21/400]³

P=59826×421/400×421/400×421/400

P=59826×400/421×400/421×400/421

P=51312 approximately
