Question

the numbers 272738 and 232342,when divided by n, a 2 digit number leave a remainder 13 and 17 respectively.Find the sum of digits of n?

Answer 1

Can't answer it as it's little bit confusing

Answer 2

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
