If the eight digit number 2575d568 is divisible by 54and 87 the value of d is ??

Answer»

54 = 2×3×3×3=2×3^3

87 = 3 ×29

The eight digit NUMBER 25,75d,568 must be divisible by 2 , 27 and 29.

So as to make it divisible by 27, it must be divisible by 3 at least.

From the divisibility rule for 3, the total of the digit must be divisible by 3.

Hence, 2 + 5 + 7 + 5 + d + 5 + 6 + 8 = 38 + d

d must be a SINGLE digit. So,

d = 1, 4 or 7.

But , if d = 1 and 4 then 25751568 and 25754568 are not divisible by 29.

47.	if are in AP, then x is equal to
Answer» ANSWER: Value of x is EITHER - ⅔ or + 1 Step-by-step EXPLANATION: In an A.P., the comman difference is always same. → 9x² - 1 = d → 4x + 21 - 3x² - 14 = d → - 3x² + 4x + 7 = d Since both equations have same R.H.S. → - 3x² + 4x + 7 = 9x² - 1 → 0 = 12x² - 4x - 8 On factorising, → 0 = 12x² - 12x + 8x - 8 → 0 = 12x(x - 1) + 8(x - 1) → 0 = (12x + 8)(x - 1) Each getting zero, → x = - ⅔ and + 1

if are in AP, then x is equal to

Answer»

ANSWER:

Value of x is EITHER - ⅔ or + 1

Step-by-step EXPLANATION:

In an A.P., the comman difference is always same.

→ 9x² - 1 = d

→ 4x + 21 - 3x² - 14 = d

→ - 3x² + 4x + 7 = d

Since both equations have same R.H.S.

→ - 3x² + 4x + 7 = 9x² - 1

→ 0 = 12x² - 4x - 8

On factorising,

→ 0 = 12x² - 12x + 8x - 8

→ 0 = 12x(x - 1) + 8(x - 1)

→ 0 = (12x + 8)(x - 1)

Each getting zero,

→ x = - ⅔ and + 1
