Question

3. Beth went to the market and bought 12 kg of sugar for 25. How much would she have to pay for 500 gm?​

Answer 1

Step-by-step explanation:

because, 12kg sugar=₹25

therefore 1 kg sugar=

$\frac{25}{12}$ because one kg= 1000g

therefore 500g= 0.5 kg

hence 500 g sugar=

$\frac{25}{12} \times 0.5 = 1.04rs$

Answer 2

Beth will pay 1.041 (currency) for 500 gm of sugar.

•As mentioned in the question Beth pays 25 currency for 12 kg of sugar.

•By Using Unitary Method: 1kg = 1000gm.

•12 kg or 12000gm sugar costs 25

•1 kg or 1000gm sugar costs 25÷ 12000

•500 gm sugar costs (25÷12000) ×

500 = 1.0416

•Thus Beth will have to pay 1.041 currency for purchasing 500 gm of sugar.

• Unitary method is generally used for solving problems , when coat if x kg is given and y kgs is to be found out.

• First the cost of 1 kg is to be found out then the y kgs.
