45 Indian Rupees

Step-by-step explanation:

P=18000rs

P=18000rsR=10%

P=18000rsR=10%T=1 year

SI=PxRxT/100

18000x10x1/100=1800rs

Compounded Half-Yearly

P =18000 rs

P =18000 rs ,T=2 half years

P =18000 rs ,T=2 half yearsR=5%

A=P[1+R/100]^t

=18000[1+5/100]^2

=18000[21/20]^2

=18000x21x21/400

=45x441=19845rs

CI=19845-18000=1845rs

Money he gained=1845-1800=45rs
