A problem by abhishek mukherjee
there are 180 circuits in a lab , each circuit contains 15 wires and 20 bulbs(all circuits are of same kind)calculate ratio of total no. of wires : total no. of bulbs..
the answer will come in the form of a:b , if a+b = x then,
what is tan 9*(x+3) degree

total no of wires = 180* 15= 2700
total no of bulbs = 180*20=3600
ratio= 3:4
given ; a+ b = x, 3+4=7 so x = 7
tan 9*(x+3) degree
= tan 9*(7+3)
= tan 90 degree which is not defined.....
hence proved
