Question

12 crates have 60 plates in each. When they are opened 2/5 of total plates are found broken .how many plates are left intact

Answer 1

Since there are 12 crates with 60 plates in each. Hence, total number of plates are = 60*12= 720 plates

No of broken plates = 2/5 of total plates = 2/5 * 720 = 288 plates

So total number of plates intact = total number of plates - number of broken plates = 720 - 288 = 432 plates
