Question
What is the role of business firms in an economy?
Solution
Firms are one of the three crucial elements in the circular flow of money through the economy. In economics, producers are often referred to as firms or companies that play a role in using inputs and producing goods and services. Firms play a key role in deciding what to produce and how to produce.
1428 ÷ 17 = ? % of 120
? + 156 ÷ 3 × 7 = 35% of 400 + (13)2
(25 × 12 + 30 × 8 – 22 × 10) = ?
(22% of 1500 + 15% of 2200) = ? x 11

20% of 1500 – 75% of 200 = 125% of ?
Simplify the following expression and find the final value:
(18 ÷ 6 of 2 + 7 of 5) ÷ 5
(7/4×18/21)+ (51/7× 28/17) + (25/2 × 48/10) =?
What will come in the place of question mark (?) in the given expression?
(5/8) × 1600 + (2400 ÷ 25) = ?
