Question

A man saves Rs 400 more each
year than he did the year
before. If he saves Rs 2000 in
the first year then in how
many years will his saving be
Rs 97200 altogether?​

Answer 1

Answer:

Step-by-step Sum of the series would be 116000 − 9600 = 106400. If we remove the 19th year's savings the savings would be 106400 − 9200 which would go below 100000. Thus, after 19 years his savings would cross 100000.
