Dear Student,

Simple interest formula is SI=PRT100Now Amount=P+SI (interest+the initial amount invested)apply the values from the questionT=3 years, P=1250,A=15501550=1250+1250×R×3100⇒1550-1250=1250×R×3100⇒300=1250×R×3100⇒100=1250×R100⇒1250×R=10000⇒R=100001250⇒R=8%Now using this interest rate we need to calculate amount for 3200 after 4 yearHence Amount=3200+3200×8×4100=3200+32×8×4=3200+32×32=3200+1024=4224Hence answer is 4224 rupees
