Question

Saksham bought 4 sweaters for Rs 1000. His friend Raja bought 3 sweaters for Rs 900. Who out of the two made a good buy?

Answer 1

Hint: First, we will now divide 1000 by 4 to find the amount Saksham paid for 1 sweater, and then we will divide 900 by 3 to find the amount Raja paid for 1 sweater. Then we will compare the price of both to find which one of them made a good buy.

Complete step by step answer:

We are given that Saksham bought 4 sweaters for Rs 1000. His friend Raja bought 3 sweaters for Rs 900.
Now, when Saksham bought 4 sweaters for Rs.1000.
So, we will now divide 1000 by 4 to find the amount he paid for 1 sweater, we get
\[ \Rightarrow \dfrac{{1000}}{4} = {\text{Rs. }}250\]
Thus, the amount of Saksham paid for one sweater is Rs. 250.
Now, when Raja bought 3 sweaters for Rs. 900.
Then we will now divide 900 by 3 to find the amount he paid for 1 sweater, we get
\[ \Rightarrow \dfrac{{900}}{3} = {\text{Rs. }}300\]
Thus, the amount of Raja paid for one sweater is Rs. 300.
After comparing the prices paid by both Saksham and Raja, Saksham got sweaters at a cheaper price.
Hence, Saksham had a good deal.

Note: Students multiply 1000 by 4 instead of dividing and also multiply 900 by 3 instead of dividing leads to a wrong answer. So we have to be really careful while calculations. We should know that the one who made a good buy will be the one who paid a lesser amount for the sweater than others.
