Answer 1

The correct option is A

Irrational

Cost of $3\frac{2}{5}$ meters of cloth = ₹ $63\frac{3}{4}$

$\therefore$ Cost of 1 meter of cloth = ₹ $63\frac{3}{4}$ $÷$ $3\frac{2}{5}$

= ₹ $\frac{255}{4}$ $÷$ $\frac{17}{5}$

= ₹ $\frac{255}{4}$ $\times$ $\frac{5}{17}$

= ₹ $\frac{15}{4}$ $\times$ 5

= ₹ $\frac{75}{4}$

= ₹ $18\frac{3}{4}$
