orally karna hai toh consider there is 15*14=210 units totally So the milk from first mixture will have 8*14=112 milk from the second mixture will have 5*15=75. But milk should originally have been 210/2=105 First mixture has 112-105=7 Second mixture has 105-75=30 Hence the ratios should be inversed to get the correct combination hence 30:7
OA: 30:7 That's right. Tell me where am I wrong ( Must be fundamentally wrong somewhere )Mix-1: Milk = 8ml, Water = 7 mlMix-2: Milk = 5ml, Water = 9mlRatio: k:18k + 5 / (5k + 9) = 1from here, k = 4Hence ratio = 4:1You can also check it by putting the value of "k" Please tell me where am I going wrong.@abhishek.2011 Tum b dekho bhai..
7k+9. Aage dekha nahin...pehle yeh correct karo. regards scrabbler
First one is divided into 8 + 7 = 15 parts, second in 5 + 9 = 14 parts. So take 210 (LCM of 14 and 15) parts. Now milk in first solution is 14 x 8 = 112, second is 15 x 5 = 75 and we need 1:1 i.e. 105 out of 210 parts milk. So see the difference of 112 and 75 from 105 - they are 7 and 30 so reverse this and voila, 30:7 is the ratio required. regardsscrabbler

Yes it's absolutely flawless agreed! Please have a look at following thing:
Forget the question for sometime:
Mix-1 : Milk = 8ml and Water = 7ml ( Ratio = 8:7)
Mix 2: Milk = 5ml and Water = 9ml (Ratio = 5:9)
Mix these 2 in 4:1
Milk = 37 and Water = 37
Ratio = 1:1
Ab idhar to kuch galat ni h, but it satisfies the question perfectly.. ??

Hence ratio = 15k : 14 = 60 : 14 = 30 : 7
(The way you have taken them total volumes are not k and 1, instead they are 15k and 14)

Correct hai...but what you forgot is that the mix-1 ka 1 unit is 15 ml and mix 2 ka 1 unit is 14 ml...you are asked ratio of quantity na...
So mixing 4 : 1 means 15 * 4 : 14 *1 = 60:14 = 30:7.... regards scrabbler
A similar question to the one posted previously: A test consists of 4 sections. Eac section has a maximumof 45 marks. Find the number of way in which a student can qualify the test if the qualifying marks is 90. 1) 36546 2) 6296 3) 64906 4) None of these

Purrfect! 😃 *Contemplating to buy HSC Mathematics book*
A dice is rolled six times. One, two, three, four, five and six appears on consecutive throws of dices. How many ways are possible of having 1 before 6?1) 1202) 3603) 2404) 280
7k+9. Aage dekha nahin...pehle yeh correct karo.
