Question

There are 50 plates in a crates and there are 11 such crates. When they are open 2/5 of the plates are f found to be broken. How many plates are left in tact

Answer 1

total number of plates=no.of plates in one crate * no.of crates = 50*11

now broke plates are 2/5 * total plates

so left plates are 3/5 * total plates

= 3/5 * 50 * 11

=3*10*11

=330

Thanks......
