Question

Neela saves in a ‘Mahila Bachat Gat’ Rs 2 on the first day of February, Rs 4 on the second day, Rs. 6 on the third day and so on. What will be her savings in the month of February 2010?

Answer 1

Neela’s daily savings of February 2010 are as follows : 2, 4, 6, ... 

This sequence is an A.P. with

a = 2, d = 4  2 = 2, n = 28

(\(\because\) Feb 2010 had 28 days as 2010 was not a leap year)

\(\therefore\) Neela’s saving in the month of February 2010 will be Rs. 812.
