Answer 2

Given:

Principal (p) = Rs 48400

Amount (A) = Rs. 52900

Time (t) = 2 years

To Find:

Rate percent

Solution:

As we know that

Amount (A) = Principal*(1+r/100)^t

Where

r is the rate of interest and t is the time

According to question

Amount (A) = Principal*(1+r/100)^t

=>52900 = 48400*(1+r/100)^2

=>52900/48400 = (1+r/100)^2

=>(23/22)^2= (1+r/100)^2

=>(23/22)-1 = r/100

=>(23-22)/22 = r/100

=>1/22 = r/100

=>1/22 = r% ( As x% = x/100)

=>r% = 4(6/11) %

Hence, Rate percent is 4(6/11) % (option (d))
