Answer 2

Answer:

the numbers are 21 and 16   (or)

the numbers are 22 and 20

Step-by-step explanation:

2a*ab = ccb

here by comparing the units digits,

either a = 1 or b = 0

as 1*b = b  and a*0 = 0 = b

if a = 1, then 2a is 21

we have 21*1b ends with b and has the 100th and 10th place value equal in the product,

1b is a number from 10 to 19

21*10 = 210  

21*11 = 132

21*12 = 252

21*13 = 273

21*14 = 294

21*15 = 315

21*16 = 336  ( satisfies the condition 2A*AB = CCB )

21*17 = 357

21*18 = 378

21*19 = 399

so, if a = 1 then, b = 6 and c= 3

and the numbers are 21 and 16

if b = 0, then ab is a0 ie., ao is a multiple of 10

we have 2a*a0 ends with 0 and has the 100th and 10th place value equal in the product,

ao is a multiple of 10 from 10 to 90

21 * 10 = 210

22 * 20 = 440  ( satisfies the condition )

23 * 30 = 690

24 * 40 = 960

25 * 50 = 1250  ( not a 3 digit number )

so, if b = 0 then, a = 2 and c= 4

and the numbers are 22 and 20
