Answer

c

Explanation

(c) Effective Rate% of SI `= 10 +(10)/(2)= 15%`
Note: When interset is compunded Half- yearly .
New Rate% `= (10)/(2) = 5%`
Time `= (3)/(2)xx 2 = 3 years `
Effective Rate% of CI for 3 years = 15.7625%
Difference in Rate% = (15.7625-15) = 0.7625%
According to the question, 0.7625% of sum = Rs. 244
`"Sum"= (244)/(0.7625)xx 100` = Rs. 32,000
