(180×100)/15= 1200. Now, (1200×100)/15= 8000 ans

CI and SI for 1st yr is the same. So the difference is due to the interest we received on the extra compound interest of 2nd yr. That is 15% = 180. So 100% will be 1200. Now it's the interest for a year and it's 15% of the total sum. So, if 15%= 1200. Then 100% will be 8000
