• The average price of 80 mobile phones is ₹ 30,000.
• The average price of remaining 78 mobile phones is ₹ 29,500.
• The cost of the highest mobile is ₹ 80,000.

To Find :-

• The cost of lowest price mobile is:

Solution :-

The average price of 80 mobile phones is ₹ 30,000.

⇛ Price of 80 mobiles = 80 × 30, 000 = ₹ 24, 00, 000

Price of Highest mobile = ₹ 80000

Let Price of Lowest mobile = ₹ x.

After, selling mobile of lowest and highest price, the average price of remaining 78 is ₹ 29, 500.

Now, According to statement

80000 + x + 29, 500 × 78 = 24, 00, 000

⇛ 80000 + x + 23, 01, 000 = 24, 00, 000

⇛ x + 23, 81, 000 = 24, 00, 000

⇛ x = 19, 000

⇛ Lowest cost Price of mobile = ₹ 19, 000.
