Question

Varun purchased a mobile phone for Rs 7,000 on which GST charged is $$12\mathrm{\%}$$ and some accessories for Rs 600 in which GST charged is 5%. Find the total amount paid by Varun.

Answer 1

Hint: We can find the GST of the mobile phone by calculating the given percentage of the price. Then we can add the GST to the price to get the amount paid for the mobile phone. Then we can find the GST of the accessories with the given percentage and add to the price of the accessories to get the total price for accessories. Then we can add the total prices for the mobile phone and accessories to get the total amount he paid.

Complete step-by-step answer:
In the question it is said that Varun purchases a mobile phone and some accessories. We are given the price and GST charged for both mobile phones and the accessories.
Let ‘CP’ be the cost of purchasing the mobile phone. It is given that,
 $$CP=Rs.7000$$
The GST charged on this product is given as,
 $GST=12\mathrm{\%}$
Therefore, the total GST on the mobile phone will be,
 $GST={\displaystyle \frac{12}{100}}\times 7000$
 $GST=Rs.840$
Hence the total amount paid by Varun for the mobile phone will be,
 Total amount for mobile phone$=7000+840$
Total amount for mobile phone Rs 78450
Now let us consider the case of accessories.
The cost of purchasing of accessories is given to us,
 $CP=Rs.600$
The GST charged on this product is,
 $GST=5\mathrm{\%}$
Therefore, the total GST on the accessories will be,
 $GST={\displaystyle \frac{5}{100}}\times 600$
 $\Rightarrow GST=Rs.30$
Hence the total amount paid by Varun for the accessories will be,
Total amount for accessories $=600+30$
Total amount for accessories =Rs 630
Now we can calculate the total amount paid by Varun for the accessories and the mobile phone.
Total amount paid $=7840+630$
$$\Rightarrow$$Total amount paid=Rs 8470
Therefore, the total amount paid by Varun is Rs 8470.


Note: Alternate solution to the problem is given by,
It is given that GST of $12\mathrm{\%}$is charged for the mobile phone. So, the total cost of the phone is given by,
Total cost of mobile phone $=112\mathrm{\%}\times CP$
It is given that $$CP=Rs.7000$$ , on substituting, we get,
 $={\displaystyle \frac{112}{100}}\times 7000=7840$
Total amount for mobile phone Rs 7840
It is given that $$5\mathrm{\%}$$ of GST is charged for accessories.
So, the total cost of accessories $=105\mathrm{\%}\times CP$
It is given that $$CP=Rs.600$$ , on substituting, we get,
 $={\displaystyle \frac{105}{100}}\times 600=630$
Total amount for mobile phone Rs 630
The total amount paid by Varun is given by the sum of the price of mobile and the accessories
 Total amount paid$=7840+630$
$$\Rightarrow$$Total amount paid=Rs 8470
Therefore, the total amount paid by Varun is Rs 8470
