**Ques:- A certain type of mixture is prepared by mixing brand A at Rs.9 a kg. with brand B at Rs.4 a kg. If the mixture is worth Rs.7 a kg., how many kgs. of brand A are needed to make 40kgs. of the mixture?**

**Recent Answer**: :

Answer:

24

Step-by-step explanation:

A + B = 40.

And at Rs 7 a kg for 40 kg, you want a total of Rs.280.

So the second equation is 9A + 4B = 280

From the first equation: B = 40 – A

and sub into the second equation:

9A + 4(40-A) = 280

9A + 160 – 4A = 280

5A = 120

A = 24.

And you should check: B should equal 40-24 = 16. Check with the final equation: 9*24 + 4*16 = 216 + 64 = 280. So it works.

Your answer, of course, is A = 24

**Ques:- Two trains of equal length when moving in opposite direction takes 5 sec. to cross each other completely and when moving in same direction takes 15 sec. Find the ratio of their speed.**

**Recent Answer**: :

Let’s assume the length of each train is ‘L’ and the speeds of the two trains are ‘V₁’ and ‘V₂’ respectively.

When the trains are moving in the opposite direction, their relative speed is the sum of their individual speeds. The total distance they need to cover is the sum of their lengths. Since they cross each other completely in 5 seconds, we can set up the following equation:

(V₁ + V₂) × 5 = 2L

When the trains are moving in the same direction, their relative speed is the difference between their individual speeds. The total distance they need to cover is the difference between their lengths. Since they cross each other completely in 15 seconds, we can set up the following equation:

(V₁ – V₂) × 15 = 2L

Now, let’s solve these equations to find the ratio of their speeds.

From the first equation, we have:

(V₁ + V₂) × 5 = 2L

V₁ + V₂ = (2L) / 5

From the second equation, we have:

(V₁ – V₂) × 15 = 2L

V₁ – V₂ = (2L) / 15

Let’s add these two equations together:

V₁ + V₂ + V₁ – V₂ = (2L) / 5 + (2L) / 15

2V₁ = (6L + 2L) / 15

2V₁ = (8L) / 15

V₁ = (4L) / 15

So, the speed of the first train is (4L) / 15.

Now, let’s substitute this value back into the first equation to find V₂:

(4L) / 15 + V₂ = (2L) / 5

V₂ = (2L) / 5 – (4L) / 15

V₂ = (6L – 4L) / 15

V₂ = (2L) / 15

Therefore, the speed of the second train is (2L) / 15.

The ratio of their speeds is given by:

(V₁ / V₂) = ((4L) / 15) / ((2L) / 15)

(V₁ / V₂) = 4L / 2L

(V₁ / V₂) = 2

So, the ratio of their speeds is 2:1.

**Recent Answer**: :

one cat kill one rat six minutes

so 1 cat kill 100 rat willbe needed 6*100=600minutes

then 100 rates kill 50minutes means then 600/50=12

so the answer is 12
