2. Step-by-step explanation:

   WE KNOW THAT,

   FEBRUARY 2010 IS NOT A LEAP YEAR

   , THEREFORE THERE WILL BE 28 DAYS IN THE MONTH OF FEBRUARY

   AS PER GIVEN DATA

   a=2 , d=2 , n=28

   Sn = S28 =?

   Sn = n/2 [2a+(n-1)d]

   S28 = 28/2 [2×2+(28-1)2]

   S28 = 14 [4+27×2]

   S28 = 14 [4+54]

   S28 = 14 × 58

   S28 = 812

   ANS :- THE TOTAL SAVINGS IN THE MONTH IF FEBRUARY, 2010 IS ₹812 .
