Explanation

To determine the relationship, we can break down the family structure:

B and D are sisters: The problem states D is B's sister.

A is B's daughter: This establishes B as the mother of A.

E is D's son: This establishes D as the mother of E.

A and E relationship: Since A's mother (B) and E's mother (D) are sisters, A and E are the children of siblings.

Therefore, A is the cousin of E.

Explanation

The day starts on Monday, and then there will be 5 Mondays in one month... E.g. Monday+6 days = 7 days Monday + 6 days= 7 days Monday + 6 days = 7 days Monday + 6 days = 7 days These are 28 days.. The next day will be Monday and Tuesday.. Then the total days will be 30 days.. According to this Mondays are 5 so the total is 5*450= 2250 Other days are 120*25= 3000 Total 2250+3000=5250 5250/30 = 175

Explanation

We're given:

1. A + B + C = 112
2. B = A - 12
3. C = 2B

We can substitute B in the first equation using the second equation:

A + (A - 12) + C = 112 2A + C - 12 = 112 2A + C = 124

Now, we can substitute C using the third equation:

2A + 2B = 124

We know B = A - 12,

so: 2A + 2(A - 12) = 124 2A + 2A - 24 = 124 4A = 148 A = 37

Now we can find B and C: B = A - 12 = 37 - 12 = 25 C = 2B = 2 * 25 = 50

Therefore, C gets $50.

Explanation

Total distance:

• Length of the train: 99m
• Length of the station: 231m
• Total distance = Length of the train + Length of the station = 99m + 231m = 330m

Total time: 11 seconds

Speed:

• Speed = Distance / Time
• Speed = 330m / 11s = 30 m/s

Now, we need to convert m/s to km/h:

• 1 m/s = 3.6 km/h

So, 30 m/s = 30 * 3.6 = 108 km/h

Therefore, the speed of the train is 108 km/h.

Explanation

The total food required for $x$ cows over 150 days is:

$$\text{Total food}=x\times 150$$

When the number of cows is reduced by 10, i.e., $x - 10$, the food lasts for 10 more days, meaning it lasts for 160 days. So, the total food required for x-10 cows over 160 days is:

$$\text{Total food}=(x-10)\times 160$$

Since the total amount of food remains constant in both cases, we can equate the two expressions for total food: x

$$x\times 150=(x-10)\times 160$$
