Answer:
48
Step-by-step explanation:
Let d represent the number of sweets Dora has to start with. Then 2d is the number Harini had. After they each ate 18, the ratio of their numbers is ...
(2d -18)/(d -18) = 5/1
2d -18 = 5(d -18) . . . . . multiply by d-18
72 = 3d . . . . . . . . . . subtract 2d-90
24 = d . . . . . . . . . divide by 3
2d = 48
Harini started with 48 sweets.
Answer: (D) 11
Step-by-step explanation:
Let the first digit x composed of ab and the second digit y composed of reversed of ab =ba
The sum of x and y will be
x+y = ab+ ba
x+y= (10.a + b) + (10.b +a)
x+y= 10a+b+10b+a
x+y= 11a+11b
By factorization
x+y= 11(a+b)
Therefore 11 is compulsory factor of x and y
