For question 49 , option 2 is better
Take option 1 - Rs 112 , and calculate principal amount by SI formula .
P = 100
Come to the second option ,
SI for 9 months = 100 * .12 * 9/12 = 9
So after 9 months you get 109 amount. However you have received just 55 and have kept Rs 54 ( 109-55=54 ) in the bank. So calculate SI for 3 months = 54* 12/100*3/12 = 1.62
So in total you should get , 54+1.62 , but you are getting 56 . So this option is more feasible.
