Question

33. During a Winter sale in a showroom the
price of different items are reduced. The
Marked price of a woodland jacket is Rs
4520. A discount of 40% is announced on
sales. What is the amount of discount on
it and its sale price.
​

Answer 1

Answer:

Step-by-step explanation:

ist (Marked) Price of the frock = 220, Rate of discount =20%

Amount of discount =10020×220

                              = 44

∴ Selling Price of the frock = Marked Price − Discount

                        =220−44

                        = 176.

Answer 2

Answer:

Students use algebra to solve equations (of the form px + q = r and p(x + q) = r where p, q, and r are specific rational numbers); using techniques of making zero (adding the additive inverse) and making one (multiplying by the multiplicative inverse) to solve for the variable.

Students identify and compare the sequence of operations used to find the solution to an equation algebraically, with the sequence of operations used to solve the equation with tape diagrams. They recognize the steps as being the same.

Students solve equations for the value of the variable using inverse operations; by making zero (adding the additive inverse) and making one (multiplying by the multiplicative inverse).
