The number 3 divides ‘a’ with a result of ‘b’ and a remainder of 2.
The number 3 divides ‘b’ with a result of 2 and a remainder of 1.
What is the value of a?
Answer: D
Since 3 divides b with a result of 2 and a remainder of 1, b=2×3+1=7.
Since number 3 divides a with a result of b (which we now know equals 7) and a remainder of 2, a=b×3+2=7×3+2= 23.
