Answer 2

Answer:

• A. 48

Step-by-step explanation:

Divisible by 9:

• 252 (9X28), 261, 270, 279, 288, 297, .....495 (9X55)
• 28 numbers are there in total

Divisible by 11:

• 253, 264, 275, 286, 297, 308, 319, 330, 341, 352, 363, 374, 385, 396, 407, 418, 429, 440, 451, 462, 473, 484, 495= 23
• Rule of divisibility for 9 says, if the sum of digits is divisible by 9 then the number must be divisible by 9

So now,

• 23-3=20

Total:

• 28+20=48
