Answer :

Solution :

Given : The price of an item is 10% cheaper in an online store S compared to the price at another online
store M.
Delivery charges of an item at the online store S and M is ₹150 and 0 respectively.
Cost of an item from the online store S is ₹100 less than the item from online store M.
Let, the price of an item at the online store M is ₹ x.
Then price of an item at the online store S is (x – 0.1x) = 0.9x

So, x – (0.9x + 150) = 100
0.1x – 150 = 100
0.1x = 250
x = 250

The price of the item at the online store S (in ₹ ) without any delivery charges is,
0.9x = 0.9×250 = 2250
Hence, the correct option is (D).
