Question
A mixture of milk and honey is being sold at the price
of pure milk, yielding a 20% profit. If 5 liters of honey is added to this mixture, the milk-to-honey ratio becomes 5:2. Determine the initial quantity of the mixture before the additional honey was added.Solution
ATQ, Profit earned is 20% which means quantity of honey in the mixture is 20% of quantity of milk.Ratio of milk to honey in the mixture = 100: 20 = 5: 1 Let initial quantity of milk and honey in the mixture is 5m and m respectively. ATQ, 5m/(m+5) = 5/2 10m = 5m + 25 m = 5 Initial quantity of that mixture = 5m + m = 6m = 30Â litres

Evaluate: 144 ÷ 12 × 6 + 35 − 4²
What will come in the place of question mark (?) in the given expression?
21 × 18 + ? – 19 × 15 = 25 × 24
2916 ÷ 54 = ? + 27
√324 + √484 + 63 = ?2Â
What will come in the place of question mark (?) in the given expression?
{(2/15) + (12/25)} of 375 + 190 = ?% of 375
- What will come in place of the question mark (?) in the following questions?
100−[20+4×5]=? (72 × 52 + 1555 )/(79+60) = 2000 ÷ ?
72 × 2 = ? + 104 – 14
672 ÷ 28 × 24 + 363 – 309 =?
