Answer 2

Answer:

Krishna income per 1 year = 4,32,000

12 months = 1 year

1 month = 1/12 year

and for 9 months = 9 x (1/12)

                             = 9/12

Krishna income in 9 months = 9/12 x 432000

                                                = Rs.3,24,000

For 15 months , we can write it as 1 year + 3 months

Krishna Income for 15 months = 4,32,000 + (3/2 x 4,32,000)

                                                  = 4,32,000 + 108000

                                                  = Rs. 5,40,000
