Question

please answer my question

Answer 1

1. Cost of 14m cloth = 1890
cost of 1m cloth = 1890 / 14
= 135
Cost of 6m cloth= 135 × 6
= 810.
2. 12 soaps costs = 285.60
1 soap will cost = 23.80
15 soaps will cost = 357
3. Cost of 9kg rice = 327.60
Cost of 1 kg rice = 36.40
cost of 50kg rice = 1820

Answer 2

1Sol )
$cost \: of \: 14m \: clothes \: = rs1890 \\ cost \: of \: 1m \: of \: cloth \: = \: \frac{1890}{14} = rs135 \\ therefore \: cost \: of \: 6m \: of \: cloth \: = 6 \times 135 \\ \: \: \: \: \: \: rs810$
2sol)
cost of one dozen of soap = rs280.60
cost of one soap =285.60/12
=23.8
therefore cost of 15 soaps = 15 × 23.8
= rs357
3sol)
cost of 9kg of rice =rs327.60
cost of one kg of rice = 327.60/9
=rs36.4
therefore cost of 50kg of rice = 36.4 × 50
= rs1820
