The options for this question are missing. Here are the missing options:
a. 7
b. 8
c. 5
d. 4
Answer
As remainder is 13 & 17 so dividend must be greater than 17
272738 = n*a+13 => 272725=n*a ---(1)
232342 = n*b+17 => 232325=n*b ---(2)
Last two digit of (1)&(2) is 25 so n must be 25, no other two digit no. greater than 25 satisfies this
272725=25*10909
232325=25*9293
n=25, sum of digits of n = 2+5 = 7
So the correct answer is option A: 7
