What is the third term in a sequence of numbers that leave remainders of 1, 2 and 3 when divided by 2, 3 and 4 respectively?
A
11
B
17
C
19
D
35
Answer
35
Explanation
Solution
L.C.M. (2,3,4) = 12
Number of the form that leave remainders of 1, 2 and 3 when divided by 2, 3 and 4 respectively =12x−1
Therefore,(2−1)=(3−2)=(4−3)=1, where x is a natural number
Thus, the third number =12(3)−1=35
The correct answer is (D): 35
