Question

In the above table, the value of 'a' is

• A. 1500
• B. 1700
• C. 1800
• D. 2000

Answer 1

The correct option is C 1800

Using the table, we get the relation between cost and weight of grain is:
cost = (weight x 100) - 200

So, when weight of grain is 20 kg,
$\therefore$ cost = (20 x 100) -200
= 2000 - 200
= ₹1800
