food of dog for 1 day = 35/60
7 dogs are left now
so total cans required = 35*7*12/60 = 49 Ans C

My problem approach will be like this:-Diet of dog per day = 35/60 cans[In this type of problems it is better to solve by unitary method like considering for per day per dog etc.]
For 12 days and 7 dogs we have 12 x 7 x 35/60 = 49 C.
