DIPANKAR C) 10 LET THE QUANTITY WHICH IS DIRECTLY PROPROTIONAL BE Q. NOW Q=K*(NO OF PASSENGERS)(WHERE K IS A CONSTANT)
NOW Q=10 WHEN N=5 SO 10=K.5........... (i)
so for no movement of the car speed should reduced by 20kmph so 20=k.x(where x is minimum passengers required). ............(ii)
so dividing eqn (i) by eqn (ii) we get x=10 whcih is the required answer.
