Find the least number which when divided by 5, 8, 11, 15 and 18 leaves the same remainder 7 in each case.
Answer & explanation
Correct answer: option 3
Required number must be the L.C.M of 5, 8, 11, 15 and 18 with an addition of 7.
Now,
L.C.M. of 5, 8, 11, 15 and 18 = 3960
So, required number = (3960 + 7)
⇒ 3967
