A lighting store is stocked with 410 fixtures. Some of the fixtures are floor lamps and the rest are table lamps. If 5% of the floor lamps and 30% of the table lamps are imported, what is the smallest possible number of imported lamps stocked at the store?
Choose the correct choice from the following options.
A) 3 B) 10 C) 13 D) 20 E) 23
F + T = 410   Now, expression for the no. of imported items = 0.05F+0.3T   =&gt; 0.05F+0.3(410-F)=123-0.25F   =&gt;F has to be a multiple of 4   to minimize the expression, we have to maximize F   Max value of F can only be 400, as anything beyond this (404 or 408) will give a fractional value of the no. of imported Ts   Hence, minimum no. of imported stuff = 123-400/4=
