Question

beth went to the market and bought 1.5kg sugar for ₹25 .how much would she have to pay for 500gm

Answer 1

Answer:

$\red { Beth \: has \: to \: pay } \green {= Rs\: 8\frac{1}{3}}$

Step-by-step explanation:

We know if the number of kilogrammes of sugar bought decreases then the cost also decreases.

Therefore, cost of sugar directly varies with the number of kilogrammes.

$So, \frac{x_{1}}{y_{1}} = \frac{x_{2}}{y_{2}}$

$Here, x_{1} = 1.5 \:kg , \:y_{1} = Rs \: 25\\</p><p>x_{2} = 500\: gram = \frac{1}{2} \:kg , \:y_{2} = \red {?}\:Rs$

$By \:substituting ,\\\frac{1.5}{25} = \frac{\frac{1}{2}}{y_{2}}$

$\implies y_{2} = \frac{1}{2} \times \frac{25}{1.5}\\= \frac{25}{3}\\= Rs\: 8\frac{1}{3}$

Therefore.,

$\red { Beth \: has \: to \: pay } \green {= Rs\: 8\frac{1}{3}}$
