We are given:

• HCF of two numbers = 8

• We are asked: Which one of the following options can never be their LCM?

Let’s understand the concept first.

🧠 Key Formula:

$$\text{HCF}\times \text{LCM}=\text{Product of the two numbers}$$

So if HCF = 8, then LCM must be a multiple of 8.
Also, both numbers must be divisible by 8.

🔍 That means:
❌ The LCM can never be a number that is not divisible by 8.

Let’s take sample options to clarify (assuming sample choices like):

A) 24
B) 56
C) 60
D) 120

Now check which of these is not divisible by 8:

• 24 ÷ 8 = 3 ✅

• 56 ÷ 8 = 7 ✅

• 60 ÷ 8 = 7.5 ❌

• 120 ÷ 8 = 15 ✅

✅ Final Answer:
60 can never be their LCM (since it is not divisible by 8)

• Length of the train = 100 meters

• Length of the platform = 100 meters

• Total distance to be covered = 100 m (train) + 100 m (platform) = 200 meters

• Time taken = Not given directly (you wrote “in seconds”), so we assume you want to find time if speed is given — or vice versa.

But you asked: “The speed of the train is?” — so we must be missing the time.

Let’s assume you meant to ask:

❓ If a 100-meter-long train passes a 100-meter-long platform in 10 seconds, what is the speed of the train?

✅ Step 1: Total distance = 100 + 100 = 200 meters
✅ Step 2: Time = 10 seconds
✅ Step 3: Speed = Distance ÷ Time = 200 ÷ 10 = 20 m/s
✅ Step 4: Convert to km/h → 20 × 3.6 = 72 km/h

—

✅ Final Answer (if time = 10 seconds): Speed of the train = 72 km/h

If you have a different time value, please provide it and I’ll recalculate accordingly.
