Answer 1

Answer:

hope it helps

Step-by-step explanation:

We know A= P(1+x)ⁿ

here A-P= Rs 4200

rate of interest x= 10% = 0.1

n= Number of years= 2

So A= P(1.10)² = 1.21 x P

So A= 1.21P

So Interest = A-P

= (1.21–1.00)P

= 0.21P=Rs 4200

So P= 4200/0.21= Rs 20,000

Therefore Simple Interest for Rs 20,000 at 10% for 2- years = 20,000 x 2 x 0.1

S.I for 2- years = Rs 4,000/=
