Question

Rs 1694 is repaid after two years at compound interest. Which of the following is the value of the principal and the rate.
a) Rs 1200 , 20 percent
b) Rs 1300 ,15 percent
c) Rs 1400 , 10 percent
d) Rs 1500 , 12 percent

Answer 1

Answer:

C is the ans

CI =P(1+r/100)^n

=1400(1+10/100)^2

=1400(1.1)^2

=1694rs

Answer 2

Let consider the principal is Rs1400 and rate of interest is 10%.

then after 1st year the interest will be( Rs 1400 × 10% )= Rs140

After completing first year the principal amount will be :-

Principal + rate of interest=Rs ( 1400 + 140) =Rs 1540

In second the principal will be = Rs1540

Rate of interest will be same = 10%

Now after second year the interest will be :-

  1540 ×$\frac{110}{100}$ = Rs154

∴ After second year total repaid amount will be:-

=Principal of second year + interest after second year .

=Rs( 1540 + 154) =Rs 1694

Hence option c) matches with the question,

Ans :- Only option (c) matches with the question. there option (c) will be the correct answer.
