c. 17.5 kg
d. 18.2 kg

Answer 1

• If 12 m uniform rod weight 42 kg, then the weight of 5 m rod of the same type will be,
• a. 16.5 kg
• b. 15.2 kg
• c. 17.5 kg
• d. 18.2 kg

$\huge {\bf{\orange{\mathfrak{Answer:-}}}}$

• $\sf{12m \: uniform \: rod \: weight \: 42kg.}$

• $\sf{5m \: uniform \: rod \: weights\: = \: ? \: (x)}$

• $\sf{Cross \: multiplying,}$

• $\sf{42 \: * \: 5 \: = \: 12 \: * \: x}$

• $\sf{x \: = \: \dfrac{210}{12}}$

• $\boxed{\therefore{\sf{x \: = \: 17.5 \: kg.}}}$
