a)8136 b)9123 c)8727 d)9383
Read Solution (Total 6)
-
- lcm of 12,14,21,33,54=8316
now checking through options,
on adding 7249+8136/8316=not perfetily divisible
similarly on checking through options,(9383+7249)/8316=2
answer=9383 - 10 years agoHelpfull: Yes(14) No(1)
- lcm of 12, 14, 21, 33 & 54= 8316
Now the lowest number to satisfy thus would be => 8316-7249 =1067
But we need to check other options also, so let us add 8316
once again to 1067.
= 8316 + 1067
= 9383 Ans - 10 years agoHelpfull: Yes(8) No(1)
- Option D is the oly number adding which will be divisible by 9 so answer is 9383
- 10 years agoHelpfull: Yes(2) No(1)
- ans is d
7249+9383=16632
only no. which is divisible by 12 - 10 years agoHelpfull: Yes(0) No(0)
- 54 = 9*6
So total sum of both the numbers should be dovisible by 9
7249= 7+2+4+9 = 22 + 9+3+8+3 = 45
No other number gives sum 45
9383 is the answer. - 10 years agoHelpfull: Yes(0) No(0)
- lcm of 12,14,21,33 and 54 is 8316
and 2*8316=16632
then by the option x+7249=16632
d)9383 - 4 years agoHelpfull: Yes(0) No(0)
