## Where,

P =Principal (sum of money)R =Rate of interestT =TimeS.I =Simple interestC.I =Compound interestPR## Now,

Using identity, (a + b)² = a²+b² + 2ab on (1+ 0.01R)² ::Putting value of PR from (1) ::Therefore, Rate of interest is

6 % per annum.Putting value of R in (1) ::.Rs. 70,000Answer:to find the sum of simple interest = p×100/t×r

so 8400×100/2 = 16,800

so the simple interest sums = 16,800

then rate = i×100/p×t

8400×100/16800×2 = 50/2

25%

so the rate of interest is 25%

and now compound interest = 16,800

+ interest

16,800+8652
