Hi,

Can you please the complete question? It is incomprehensible at the moment.

please answer this

Hi Siva,

Initial count 10 coins (6 tails, 4 heads)

Final count 9 coins (5 tails, 4 heads)

Now let's list out various possibilities of flipping

Case 1: Out of 7 flipped coins, let us assume the person flipped 6 tails and 1 head ==> the resulting count is (1 tail, 9 heads), which is not a possible case as the final count mentioned in the question was different.

Case 2: Out of 7 flipped coins, let us assume the person flipped 5 tails and 2 heads ==> the resulting count is (3 tail, 7 heads), which is not a possible case as the final count mentioned in the question was different.

Case 3: Out of 7 flipped coins, let us assume the person flipped 4 tails and 3 heads ==> the resulting count is (5 tail, 5 heads), which is a possible case as the final count mentioned in the question was similar.

Case 4: Out of 7 flipped coins, let us assume the person flipped 3 tails and 4 heads ==> the resulting count is (7 tail, 3 heads), which is not a possible case as the final count mentioned in the question was different.

As we can see, only case 3 is possible. Therefore, the coin would show a head.

Hope this helps you.

Thank you.

**Cutoff mrks for AFCAT exam.**

Hi,

The cut-off marks for any exam is subjective and depends on the difficulty level of the exam and the performance of your competitors. However, for AFCAT, the cutoff usually hovers around 150 marks. So anything above 150 should be a safe score. Hope that helps.

Hi Sourav,

There can be different ratios for which the final concentration is 40%. In this question, we have to find among the options the ratio which yields in 40% concentration. Here, with the help of a & c and b & c, we have prepared 2 solutions which have 40% concentration. Adding these 2 mixtures in any ratio would yield a 40% concentration solution. But, we have to check which of the options suit. So, when we add them in 2:1 ratio, we get option A. Other options cannot be obtained.

Hope this answers your query.
