Given:

the number of men(M₁) = 550

food last for days(D₁) = 28 days

Concept:

total work before and after joining the men will be the same.

Formula used:

M₁ × D₁= M₂ × D₂

where M and D represent the number of men and days respectively.

Calculation:

Let the same amount of food be enough for D2 days

Now men(M₂) = 550 + 150

⇒ M₂ = 700

M1 × D1= M2 × D2

550 × 28 = 700 × D2

⇒ D2 = (550 × 28)/700

⇒ D2 = 15400/700

⇒ D2 = 22 days

Hence, the same amount of food will be enough for 22 days.

The logic follows here is:

The numbers here are in the alternate of square and cubes of the number in increasing order.

1² = 1

2³ = 8

4³ = 64 

5² = 25 

6³ = 216  

7² = 49

Hence, the correct answer is "216".

Decoding the given information,

After replacing the signs from left to right and using the BODMAS rule,

8 ÷ 2 + 6 × 3 - 5 = ?

4 + 6 × 3 - 5 = ?

4 + 18 - 5 = ?

22 - 5 = ?

? = 17

Hence, the correct answer is "17".

The pattern follows here is:

Hence, the correct answer is "65".
