Estimation And CostingMediumEstimation Of Lighting Scheme

Estimate the current carrying capability of a conducting wire from the main distribution board to the meter. The main distribution board has three light/fan circuits of 800 W each and two 15 A power circuits of 1.5 kW each. The safety factor and power factor are 1.5 and 0.8 respectively.

50 A

30 A

65 A

45 A

View Answer

Correct Answer: D — 45 A

Explanation:

The correct answer is D: 45 A.

Lighting/fan load: 3 × 800 = 2400 W

Power load: 2 × 1500 = 3000 W

Total load: 2400 + 3000 = 5400 W

Applying power factor: S = 5400 / 0.8 = 6750 VA

Applying safety factor: S = 6750 × 1.5 = 10125 VA

Current: I = 10125 / 230 = 45 A

Estimation And CostingEasyCosting Methods Batch Costing

Under batch costing, ___________ products are produced in a continuous production flow in lots.

Homogeneous products

Heterogeneous products

Diversified products

Manifold products

Customized units

View Answer

Correct Answer: A — Homogeneous products

Explanation:

The correct answer is A: Homogeneous products.

Under batch costing, homogeneous products are taken as the cost unit. A batch consists of a specific number of identical units processed simultaneously. Inputs accumulate in the assembly line until the minimum batch size is reached, after which all inputs in the batch are processed for further operations.

Estimation And CostingMediumIE Rules Leakage Current

What will be the value of leakage current through wire in a residential building with supply voltage of 240 volts, if a building wiring consists of 10 points of 100-watt lamps and 7 fans of 200 watts each?

1.5 A

2 A

10 mA

2 mA

View Answer

Correct Answer: D — 2 mA

Explanation:

The correct answer is D: 2 mA.

Total load: P = (10 × 100) + (7 × 200) = 2400 W

Full load current: I = P / V = 2400 / 240 = 10 A

As per IE Rules, maximum permissible leakage current = I / 5000 = 10 / 5000 = 2 mA

Estimation And CostingEasyCosting Methods Job Costing

The job costing method may be regarded as the principal method of costing since the basic object and purpose of all costing is to:

Analysis and ascertainment of cost of each unit of production

Convert loss into profit

Control and regulate cost

Both 1 & 3

Reduce taxes on production

View Answer

Correct Answer: D — Both 1 & 3

Explanation:

The correct answer is D: Both 1 & 3.

The basic object of all costing is to analyse and ascertain the cost of each unit of production, and to control and regulate cost. These principles are valid for all types of industry including printing, furniture, ship-building, and heavy machinery. Determining profitability is also an objective, but options 1 and 3 directly represent the principal purposes.

Estimation And CostingEasyEnergy Conservation Building Code

As per the amended EC Act, the minimum contract demand for a building should be:

120 kVA

100 kVA

200 kVA

80 kVA

View Answer

Correct Answer: A — 120 kVA

Explanation:

The correct answer is A: 120 kVA.

The Energy Conservation Building Code (ECBC) sets minimum energy standards for new commercial buildings having a connected load of 100 kW or contract demand of 120 kVA and above. It was developed by the Government of India on 27th May 2007 and is implemented across multiple states including Odisha, Punjab, Karnataka, Rajasthan, Maharashtra, and others.
