$\fbox\red{a) \: Simple Interest :}$

⇛Time=1 year 4 months= 4/3

⇛ Principal= Rs 6000

⇛let SI be x

⇛ Amount=Principal + Simple Intrest

⇛7500=6000+X

⇛7500-6000=X

⇛1500=X

∴ Simple Intrest =RS 1500

$\fbox\red{ RS. 1500 ✓}$

$\fbox\pink{ b) Rate Percent :}$

⇛Let rate be x

⇛SI= PRT

⠀⠀ 100

⇛1500= 6000*X*4
