If the carriage carrying load of 810 Kg, for 70 km costs Rs. 45 what will be the cost of carrying 840 Kg load for a distance of 63 Km at half of the former rate?

• the former rate is 45/(810*70)=0.00079rs/kg/km.
  half rate is 0.00039rs/kg/km
  cost of carrying 840 kg for 63 km is=0.00039*840*63=21rs

• load km cost
  810 70 112.50 ------(1)
  840 63 x --------(2)
  work and time rule
  810*70/112.50 = 840*63/x
  x=840 *63*112.50/810*70
  x=105 Rs.
  according to question at half of the former rate
  so x = 105/2
  x= 52.5
