@Aryan kumar.. Bahout pyara question h yeah.. Option se kiya karo...ya r% guess kiya karo.. Jaise isme saaf dikh rha h 20% h rate f interest.. Rate%= 20%= 1/5 5---6. for 1 st yr & for 2 year it would be (p) 25------36(amount) Ci= 11 in ratio... & in actual it is 880 rs... Mean 80 time of 11 so.. 80 time of 25 would 2000( principal) option se pick karo.. 5 sec m.. Isse bhi jaldi..

dont worry.. Aryan.. If u need basic method.. I van provide you that one also. No need to guess or hit n trial.. have u watched the last lecture of this session in which i have ecplained the shortcut to find cumulative interest... ..For 2,3,4 year... just use them like this..use them directly.. (3r^2+3r+r^3) /r^2+2r =1456/880 now solve quadratic n get thr values of rate %.. Thn aage to pata hu h tumhe.. Rate pata chla gayi fir to Principal nikal hi loge
