In a boarding house an amount of 50 naira per day is spent on feeding 35 boys. How much money is needed per day to feed 105 boys,eating at the same rate?
To find out how much money is needed per day to feed 105 boys, first calculate the cost of feeding one boy by dividing the total amount spent by the number of boys: 50 naira / 35 boys = <<50/35=1.43>>1.43 naira/boy
Then multiply the cost per boy by the number of boys to find the total cost of feeding 105 boys: 1.43 naira/boy * 105 boys = <<1.43*105=150.15>>150.15 naira. Answer: \boxed{150.15}.
