The age of the daughter is same as the digit in the mother's age, but in reverse order. In thirteen years mother will be twice as old as daughter will be then. what is the difference in their current age ? Choose the correct choice from the following answers:
A) 15	B) 23	C) 27	D) 46	E) 32
daughter's age= 10x+y   so mother's age= 10y+x..   after 13 years , 10x+y+13=2*(10y+x+13)....   so 13+19y=8x... check for odd values of y, y=1 satisfies the eqn with x=4... so ages are 41 and 14 and ans as found correctly by u is 27..27
