I would go for A.
My method :
270900 = 180000x0,07m + 180000x0,075n
270900 = 180000x0,07m+n + 180000x0,005n
270900 = 264600 + 180000x0,005n
6300 = 900n
Does it sound logical??? or am I totally wrong???
Answer as per book- is option 3
The issue with this type of problems are as u pay ur 1st instalment, principal sum should reduce while calculating 2nd instalment...we will have to take that into consideration
Try solving the problem i had posted under 'interests and instalments'...it also follows similar logic
If somebody can pls solve and explain??
