There were 740 sticks in the box (the same number at the beginning and at the end). There were 148 green sticks and 148*4 = 592 blue sticks in the box at first. Thus the problem is just solved: at the beginning, there were 148 green sticks and 148*4 = 592 blue sticks.ĪNSWER. So, there were 4+1 = 5 equal groups each group contained 740/5 = 148 sticks. HENCE, there were 740 sticks in the box at the beginning, and the ratio of blue to green sticks was 4:1. | is THE SAME as at the beginning, according to the problem. | Now notice that total number of sticks in the final state | Thus the total number of sticks in the final state is 185 + 555 = 740. This problem is good for mental solution,Īccording to the condition, in the final state, there are 185 green sticks in the box,Īnd the number of blue sticks is thrice of it, i.e. (b) find the number of green sticks in the box at first. (a) find the total number of blue and green sticks in the box, If there were 185 green sticks in the box now, The ratio of the number of blue sticks to the number of green sticks became 3:1. When David took out some blue and sticks and replaced them with an equal number of green sticks, The ratio of the number of blue sticks to the number of green sticks in a box was 4:1. (a) total number of sticks: 16y+4y initially, or 15y+5y at the end, so 20y = 20(37)=740 Since x=4y, the initial numbers of sticks were 16y blue and 4y green.Īfter y sticks were switched from blue to green, the numbers of sticks were 15y blue and 5y green.Īt the end, the number of green sticks was 185: The number of blue sticks remaining was 3 times the number of green sticks: Initially, the ratio of blue to green sticks was 4:1, soĭavid took out some blue sticks and replaced them with green sticks: Don't spend too much time trying to figure out what he was trying to do with his solution. The solution from the other (new) tutor contains several errors, including using the given information incorrectly.
