- The numbers 272738 and 232342, when divided by n, a two digit number, leave a remainder of 13 and 17 respectively. Find the sum of the digits of n?
a. 7
b. 8
c. 5
d. 4
Explanation:
From the given information, (272738 - 13, 232342 - 17) are exactly divisible by that two digit number.
We have to find the HCF of the given numbers 272725, 232325.
HCF = 25.
So sum of the digits = 7. - 7 years agoHelpfull: Yes(4) No(0)

- answer is 2
i had done in h.c.m method
dividing greater no with small no and last no i got is 2 - 9 years agoHelpfull: Yes(0) No(3)
- 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 - 8 years agoHelpfull: Yes(0) No(0)
