Paint needs to be thinned to a ratio of 2 parts paint to 1.5 parts water. The painter has by mistake added water so that he has 6 litres of paint which is half water and half paint. What must he add to make the proportions of the mixture correct?
A. 1 litre paint B. 1 litre water C. ½ litre water and one litre paint D. ½ litre paint and one litre water E. ½ litre paint
Reqd. ratio = 2 : 1.5 i.e. 4 : 3 between paint and water respectively. 6 litres of paint which is half water(3 litres) and half paint (3 litres)
Right now the ratio is 1:1 Looking at the options, A. Paint : Water = 4 : 3 which is the reqd. ratio . Correct Answer B. Paint : Water = 3 : 4 C. Paint : Water = 4 : 3.5 D. Paint : Water = 3.5 : 4 E. Paint : Water = 3.5 : 3
Answer : A

A. 1 litre paint B. 1 litre water C. ½ litre water and one litre paint D. ½ litre paint and one litre water E. ½ litre paint Hi, two ways 1) based on choicewater and paint are in ratio 1:1.. we have to make it 2:1.5 or 4:3.. so clearly paint has to be added to bring up the ratio of paint.. ONLY A and E are left Quantity P:W is 3:3 it has to be converted to 4:3.. so clearly 1 liter of P is to be added ans A 2) Proper methodexisting ratio = 3:3.. add y to convert to 4:3.. so \(\frac{3+y}{3}= \frac{4}{3}\).... \(9+3y=12.................3y=129...................y=1\) ans A

Required ratio = Paint/Water = 2/1.5 = 4/3 Right now, paint = 3 litres and water = 3 litres
lets say 'x' litres of paint need to be added to make the desired ratio. Then we have: (3+x)/3 = 4/3 Or 3+x = 4 or x = 1
Hence A answer

A. 1 litre paint B. 1 litre water C. ½ litre water and one litre paint D. ½ litre paint and one litre water E. ½ litre paint We are given that the painter needs a ratio of paint to water of 2x : 1.5x. However, he actually has 3 litres of paint and 3 litres of water, which make a ratio of 1 : 1. To make the correct ratio of paint to water, he must add more paint. We can let n = the number of litres of paint he must add. (3 + n)/3 = 2x/1.5x (3 + n)/3 = 2/1.5 1.5(3 + n) = 6 4.5 + 1.5n = 6 1.5n = 1.5 n = 1 Thus, he needs to add 1 litre of paint. Answer: A

A. 1 litre paint B. 1 litre water C. ½ litre water and one litre paint D. ½ litre paint and one litre water E. ½ litre paint Hi Bunuel , Instead of using part to part , I am using part to whole , approach, why am I not getting the answer ! \(\frac{paint }{ Total \hspace{1mm}quantity}\)=\(\frac{2}{3.5}\) > Required ratio Finally after adding x liters of paint to 3 liters of paint already present the ratio of paint to total mixture is \(\frac{3+x}{6}\) Hence equating the proportions \(\frac{2}{3.5}=\frac{3+x}{6}\) x = \(\frac{3}{7}\) Whys is x not coming to 1?

Because once you add x litres of paint to the mix, the total mix becomes 6 + x litres. Hence, \(\frac{2}{3.5}=\frac{3+x}{6+x}\) x = 1

Paint and water need to be in the ratio 2 : 1.5 which is nothing but 4 : 3. Now 6 L solution has equal amounts of paint and water ( 3 L and 3 L) and we need to bring it to the ratio 4 : 3 (P : W). Currently W is already 3 L, so if we add another 1 L of paint to the 6 L solution, the new ratio will become 4 : 3 as we require. Hence Answer is A  1 L of paint.
