Q6 of 65 Page 4

Let us construct the quadratic equations in one variable from the following statements.

One person bought some kg. sugar in ₹ 80. If he would get 4 kg. more sugar with that money, then the price of kg. sugar would be less by ₹ 1.

We know that

price = quantity of sugar in kg X rate per kg


Let the quantity be x.


Price for x kg of sugar = Rs 80


therefore,



According to question,


For the same price, Quantity has increased by 4kgs and rate has decreased by 1 .


As, price = quantity of sugar in kg × rate per kg


So,





Hence the required quadratic equation is
