Read Solution (Total 4)
-
- take L.C.M of all numbers i.e 6,9,12,17
the L.C.M is 612 therefore 612 is divisible by all numbers
so multiple of 612 will also be divisible by all the above numbers
so 612*17=9792 which is divisible by all
add 2 to 9792 to get a remainder of 2 as required in the question..
so ans is 9792+2=9794 - 8 years agoHelpfull: Yes(6) No(2)

- Apply hit and trial method at each option
9792/9= 0 remainder (failed)
9982/9= 1 remainder (failed)
9794/6= 2
9794/9= 2
9794/12=2
9793/17= 2
condition is satisfy so answer is option c - 8 years agoHelpfull: Yes(3) No(0)
- Take LCM of all the numbers 6,9,12,17 =612
and devide each option
(3) 9794 - 7 years agoHelpfull: Yes(1) No(0)
