A sum of money is invested at 20% compound interest (compounded annually). It would fetch Rs. 723 more if interest is compounded half-yearly. The sum is
Rs. 15,000
Rs. 30,000
Rs. 20,000
Rs. 20,000
B.
Rs. 30,000
Shortcut Method: Go with option and check it.. If we suppose or
take second option i.e Rs 30,000 as principal, then check it. If compound interest is annually for 2 years on Rs, 30000 then interest would be: For first year 20% on 30,000 = Rs 6000 For second year 20% on (30,000 + 6000 = 36000) = 7200 Total interest = (6000 + 7200) = Rs 13200.
When compound interest is half-yearly, then rate would be half and time would be double the given. So, For first year 10% on 30,000 = 3000
...(i) For second year 10% on (30,000 + 3000 = 33000) = Rs 3300...(ii) For third year 10% on (33,000 + 3300 = 36300) = Rs 3630 ...(iii) For fourth year 10% on (36300 + 3630 = 39930) = Rs 3993 ...(iv) Adding (i), (ii), (iii), (iv) Interest would be Rs (3000 + 3300 + 3630 + 3993) = Rs13,923Difference of both the interest is Rs (13, 923 - 13200) = Rs 723
