  • question_answer During a sale, a shop offered a discount of 10% on the market price of all the items. What would a customer have to pay for a pair of jeans market at Rs. 1450 and two shirts marked at Rs. 850 each.

    Answer:

    The market price of jeans = Rs. 1450
    Discount % = 10%
    Discount value \[=\text{ }\frac{10}{100}\times 1450\]= Rs. 145
    S.P after 10% discount \[=\text{ }1450\text{ }-145\text{ }=~\]Rs. 1305
    The market price of 2 shirts \[=\text{ }2\times 850\text{ }=~\]Rs. 1700
    \[Discount\text{ }on\text{ }two\text{ }shirts\text{ }=\frac{Rate\,\times \,MP}{100}=\frac{10\times 1700}{100}\]
    = Rs. 170                                                                                                                                             
    \[\therefore \] S. P. of two shirts = Rs. 1700 - RS.170 = Rs. 1530
    \[\therefore \]  The customer had to pay = Rs. 1305 + Rs. 1530 =Rs.2835
