**Question 1.**

**Solution:**

Cost of 14 m of cloth = Rs. 1890

Cost of 1 m = Rs. \(\\ \frac { 1890 }{ 14 } \)

and cost of 6 m = Rs. \(\\ \frac { 1890\times 6 }{ 14 } \)

= Rs. 135 x 6

= Rs. 810

**Question 2.**

**Solution:**

Cost of 1 dozen or 12 soaps = Rs. 285.60

Cost of 1 soap = Rs. \(\\ \frac { 285.60 }{ 12 } \)

Cost of 15 soaps = Rs. \(\\ \frac { 285.60\times 15 }{ 12 } \)

= Rs. 357.00

**Question 3.**

**Solution:**

Cost of 9 kg of rice = Rs. 327.60

Cost of 1 kg = Rs. \(\\ \frac { 327.60 }{ 9 } \)

and cost of 50 kg = Rs. \(\\ \frac { 327.60\times 50 }{ 9 } \)

= Rs. 36.40 x 50

= Rs. 1820
