b) the cost of 17kg of patatoes

Answer 1

Given - Cost of 8 kg potatoes

Find - a) the weight of potatoes bought for rupees 60.50.

b) the cost of 17kg of potatoes

Solution - a) Potatoes bought for Rs. 88 = 8 kg

Potatoes bought for Rs. 60.5 = $\frac{8}{88} \times 60.5$

Performing multiplication and division

Potatoes bought for Rs. 60.5 = 5.5 kg

b) Cost of 8 kg potatoes = Rs. 88

Cost of 17 kg potatoes = $\frac{88}{8} \times 17$

Performing multiplication and division

Cost of 17 kg potatoes = Rs. 187

Hence, the weight of potatoes bought for rupees 60.50 is 5.5 kg and the cost of 17 kg of potatoes is Rs. 187.

Answer 2

Concept:

Weight is the force exerted by gravity on per area of a body. The unit of weight is kilogram in $S.I.$

Given:

The cost of $8kg$ potatoes is rupees 88.

Find:

• The weight of potatoes bought for rupees $60.50$.
• The cost of $17kg$ of potatoes.

Solution:

According to the problem,

$a)$ The cost of $8kg$ potatoes is $Rs. 88$

The weight of $Rs.1$ potatoes will be $\frac{8}{88}$

Thus, the weight of $Rs.60.50$ potatoes is $\frac{8}{88} *60.50$

That is $=5.5kg$

$b)$ The cost of $8kg$ potatoes is $Rs. 88$

The cost of $1kg$ potatoes will be $\frac{88}{8}$

Then the cost of $17kg$ potatoes will be $\frac{88}{8}*17$

That is $=Rs.187$

Hence, the weight of potatoes bought for $Rs.60.50$ is $5.5kg$ and the cost of $17kg$ potatoes is $Rs.187$.
