I will mark the correct answer as brainliest

Answer 1

c.i.= a-p

345= a - 3136

a= 3136+345

=3481

A= P(1+R/100)

3481 = 3136(1+R/100)

3481-3136=1+r/100

345=1+r/100

345-1= r/100

344= r/100

r= 344×100

= 34400

r%= 34400/100

= 344%

Answer 2

Answer:Rate of interest is 5.36%

Step-by-step explanation:

P= Rs 3136

CI= Rs 345

A= Rs 3481

T=2 years

A=P(1+R/100)ⁿ

3481= 3136(1+r/100)²

3481/3136= (100+r/100)²

√(3481/3136)=100+r/100

59/56= 100+r/100

5900=56(100+r)

5900= 5600+56r

5900-5600=56r

300=56r

r= 300/56= 5.36%
