Explanation

If 25% of a certain number is 1600, we can set up an equation:

25% of x = 1600

Convert the percentage to a decimal:

0.25x = 1600

Divide both sides by 0.25:

x = 1600 / 0.25

x = 6400

So, the certain number is 6400.

Now, we need to find 10% of 6400:

10% of 6400 = 0.10 x 6400 = 640

Explanation

Let's examine the pattern of the given series: 2880, 480, 92, 24, 8, 4, 4.

Start by checking the relationship between consecutive numbers:

• 2880 ÷ 6 = 480
• 480 ÷ 5 = 96 (but the next number is 92, so this is where the error occurs)
• 92 ÷ 4 = 24
• 24 ÷ 3 = 8
• 8 ÷ 2 = 4
• 4 ÷ 1 = 4

The wrong number is 92.

It should be 96 for the series to follow a decreasing division pattern.

Hazrat Abu Bakr (R.A) was elected as the first caliph of Islam at Saqifah Bani Saedah, a place in Madinah, after the death of the Prophet Muhammad (PBUH) in 632 CE.

This event is known as the "Saqifah of Bani Saedah" or "The Gathering of Bani Saedah".

Saqifah Bani Saedah was a covered platform or a roofed building where the Ansar (helpers) gathered to discuss the succession of the Prophet Muhammad (PBUH).

The Muhajirun (migrants) later joined them, and after some discussion, Hazrat Abu Bakr (R.A) was elected as the caliph.

Explanation

3889 + 12.952 - X = 3854.002

First, combine the constants on the left side:

3901.952 - X = 3854.002

Now, subtract 3854.002 from both sides:

47.95 - X = 0

Subtract 47.95 from both sides:

-X = -47.95

Multiply both sides by -1:

X = 47.95
