Thanks for the logical question✊ !!

━━━━━━━━━━━━━━━━━━━━

GiveN:

• 522 : 98
• 722 : 392
• 222 : 32
• 552 : ?

To FinD:

• The number that replaces the question mark?

Logic:

Here, There is a super logic, Let's try this out

Left side (Number)

➝ Add the first two digits.

➝ Square the result.

➝ Multiply this result with third digit.

➝ Final result is Right side (Number)

Solution:

Here,

$\large{ \boxed{ \sf{ \red{522}}}}$

• 5 + 2 = 7
• 7² = 49
• Then, 49 × 2 = 98(Result)

$\large{ \boxed{ \sf{ \red{772}}}}$

• 7 + 7 = 14
• 14² = 196
• Then, 196 × 2 = 392(Result)

$\large{ \boxed{ \sf{ \red{222}}}}$

• 2 + 2 = 4
• 4² = 16
• Then, 16 × 2 = 32(Result)

☸ Now,

$\large{ \boxed{ \sf{ \purple{552}}}}$

• 5 + 5 = 10
• 10² = 100
• Then, 100 × 2 = 200(Required Answer)

$\large{ \therefore{ \mathrm{Correct \: answer \: is \: \boxed{ \rm{ \red{D}}}}}}$

In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six. Similarly, the ratio of lemons to oranges is 6∶8 and the ratio of oranges to the total amount of fruit is 8∶14
