Answer 2

$\huge{\mathcal{\purple{A}\green{N}\pink{S}\blue{W}\purple{E}\green{R}\pink{!}}}!$

• Principal=Rs.800,Amount=Rs.920,
• T=3years
• Simple interest =920−800=120
• ∴ Rate % =800×3120×100=5%
• If rate % is increased by 5%, i.e., if rate % = 10%, then
• SI=100800×3×10=240
• ∴Amount=Rs.800+Rs.240=Rs.1,040
• hope it will help you!!
