Write $'T'$ for true and $'F'$ for false for the following: If $10$ pipes of the same diameter can flll a tank in $24$ minutes, then $8$ pipes would fill it in $19$ min $20$ sec.
Answer
false. Solution: $10$ pipes fill the tank in $24$ min. $1$ pipe will fill the tank in $24 \times 10$ min. (Less pipes, more time taken) $8$ pipes will fill the tank in $\frac{24\times10}{8}=30\text{ min}$ (More pipes, less time taken)
