His monthly income   =  Rs.42000 (given )
household expenses = 4/7 x 42000 
                                  = Rs. 24000
conveyance               = 1/7 X 42000
                                  = Rs. 6000 
Insurance                  = Rs . 2000
monthly total expenses = 24000 + 6000 + 2000 
                                      = Rs. 32000
Monthly savings            = 42000 - 32000 
                                      = Rs. 10000

Annual savings = 12 X  10000
