If a number is subtracted from the square of its one half, the result is 48. The square root of the number is?

Let the antecedent be N.
Then, N/24 = 2/3
? N = (24 x 2) / 3
= 16

Let the number be N and (50 - N)
Then, 1/N + 1/(50-N) = 1/12
? (50 - N + N) / {N(50 - N)} = 1/12
? N² - 50N + 600 = 0
? N = 30 or 20
? the number are 20, 30

Let the required number be N,
Then, N/6 = N - 40
? N + 240 = 6N
? N = 48.

Let the requirement odd integers be N, N +2 and N + 4
Then, N + (N + 2) + (N + 4) = 57
? 3N = 51
? N = 17
? The integers are 17, 19, 21.

Let the number be 4N, 5N and 6N
Then, 4N + 5N + 6N/3 = 25
or 15N = 75
or N = 5
Then largest number = 6N = 6 x 5 = 30

Let the three consecutive numbers be x, x+1 and x+2 respectively
? Diff between first and third numbers = (x + 2) - x
= 2

Let the number be N.
Then, N - N/3 = 48
2N/3 = 48.

Here neither the remainder nor the dividend nor the second number is given. So, can't be determined.

Let the number be N
? (1/2 + 1/3 + 1/4)N = {(6 +4 +3) x N } / 12
= 13N / 12

According to the question,
13N/12 - N = 4
? N = 48

Let first and second numbers are p & q.
p/5 = 5q/8
? p/q = 25/8 ...(i)
p + 35 = 4q
or 25q/8 + 35= 4q
? q = 40.
