Question
A six-digit number 11p9q4 is divisible by 24. Then the
greatest possible value for pq is:Solution
11p9q4 will be divisible by 24 = 8 ×3 As we know the divisbility rule of 8 and 3 so take the maximum value of p and q from 1 to 9 p = 7 and q = 8 the value of pq = 7×8 = 56
Simplify:
6x + 8y - [(12x + 6y) - (4x + 3y) + 2y] - 4xIf 9x2 + 16y2 = 24xy, then find the ratio of ‘x’ and ‘y’, respectively.
- Suppose [a + (1/16a)] = 3, then the value of [16a³ + (1/256a³)] is:
If, 6x + y = 20, and 2xy = 32, and 6x > y, then find the value of 216x³ – y³.
If x + 1/x = 2, find x⁷ + 1/x⁷.
(x – 6) 2 + (y + 2) 2 + (z – 4) 2 = 0, then find the value of 4x - 3y + z.
