• A. $35$
• B. $40$
• C. $350$
• D. $400$

Answer 1

Answer: (A)

$35$

Since $149A$ is $4$-digit number, where $A$ is the digit at the one place. So, $A$ can take any value from $0$ to $9$.

Also $149\times ?$ lies in between $50,000$ and $59,000$.

Let, $A=0$ then no. $=1490$.

Option (a) $1490\times 35=52,150$ which is true.

Option (b) $1490\times 40=59,600>59,000$ which is not true.

Simply, options (c) and (d) are also not true.
