# Economics Mcqs

This set of Mechanical Engineering Multiple Choice Questions & Answers (MCQs) focuses on “ Economics ”. These Mcqs are chosen from a collection of most authoritative and best reference books on Chemical Engineering. Our aim is to prepare an individual for competitive exams like NTS, GAT, ECAT, University and College entrance exams, Jobs and interviews. One should practice our MCQS to assimilate Economics comprehensively.

## 4. If the interest rate is 5 per cent per period and the interest is compounded at half-year periods the actual annual return on the principal would be

Exactly 5 per cent

Exactly 10 per cent

Somewhat larger than 10 per cent

Greater than 5 per cent but less than 10 per cent

## 7. If S represents the amount available after n interest periods for an initial pincipal P with the discrete compound interest rate i the present worth can be determined by

Present worth = S/(1 + i)n

Present worth = S/ein

Present worth = S/(1 + in)

Present worth = S/(1 + n)

E1.1

## 9. The effective annual interest rate ieff is expressed in terms of the nominal interest rate r compounded continuously as

Ieff = In (r + 1)

Ieff = er - 1

Ieff = In r - 1

Ieff = er

## 10. For a nominal interest rate of 20 per cent compounded continuously the effective annual interest rate will be

Equal to 20 per cent

More than 20 per cent

Less than 20 per cent

Equal to or less than 20 per cent

## 11. The decision by a company management to implement a project is based entirely on

Obligation

Commitments

Economic evaluations

None of the above

## 12. Which of the following is a component of working capital investment?

Process equipment

Maintenance and repair inventory

Utilities plants

Depreciation

## 13. If the cost of an equipment of the desired capacity is not available it may be estimated from the cost of another equipment using the formula

(cost)1 = (cost)2 [(capacity)2/(capacity)1]

(cost)1 = (cost)2 [(capacity)1/(capacity)2]

(cost)1 = (cost)2 [(capacity)1/(capacity)2]0.6

(cost)1 = (cost)2 [(capacity)2/(capacity)1]0.6

## 14. The economic life of a small chemical plant is

Usually more than a large chemical plant

Usually much more than a large chemical plant

Usually much less than a large chemical plant

Always equal to a large chemical plant

## 15. Select the correct expression

Profit = revenue - operating cost

Profit = revenue - fixed cost

Profit = revenue - total cost

Profit = revenue - book value
