Question

Answer 1

here is your answer OK ☺☺☺☺☺☺☺


Let The Principal Be Rs x

P(1+R/100)n-P = 510

P[(1+R/100)n-1] = 510

P[(1+12.5/100)2-1] = 510

P[81/64-1] = 510

17P/64 = 510

P = 510* 64 / 17 = Rs 1920

SI = 1920*12.5*2/100 = Rs 480

Answer 2

Answer:

Step-by-step explanation:

Amount = P×(1+R/100)^n

= 510(1+12/100)^2

= 510×28/25×28/25

=639.744

Simple interest = 639.744×2×12/100

=153.538
