If the marginal cost function is given by MC=2(2x+9)-1/2 and the fixed cost is Rs. 4 , find the average cost for 8 units of output.

Answer»

given, The marginal cost function, M.C = 2(2x + 9)

we know, C = ∫(M.C) dx

= ∫2(2x + 9) dx

= 2√(2x + 9) + k , where k is constant.

here given fixed cost is Rs. 4

means if C= 4 then x = 0 and hence, 4 = 2√(2 × 0 + 9) + k

⇒4 = 2 × 3 + k ⇒k = -2

Thus total cost function is C = 2√(2x + 9) - 2

now average cost function A.C = total cost function/x

= C/x

= [2√(2x + 9) - 2]/x

for x = 8, A.C = [2√(2 × 8 + 9) - 2]/8 = 1

How is unlocking of phone done using software?

Answer»
  • Unlocking is a relatively simple software “patch” where a user plugs their phone into a computer and runs a small computer program. The technology is straightforward, easy to use and patches the phone very quickly. If you have ever updated an iPhone or Blackberry by plugging it into your computer - the unlocking process is usually not significantly more complex than that simple process (it can also be done with a series of codes that you enter into the phone).
  • Unlocking is a quick process to allow a phone to use SIM cards from other carriers – and thereby easily use an older phone on another carrier.

Sachin travels a certain distance at a speed of 40 km/hr in 4 hours. Tinku also travels the same distance in 16 hours. Find the speed of Tinku.1. 12 km/hr2. 16 km/hr3. 10 km/hr4. Can’t be determined

Answer» Correct Answer - Option 3 : 10 km/hr

Given:

Speed of Sachin = 40 km/hr

Time taken by Sachin = 4 hours

Time taken by Tinku = 16 hours

Formula used:

Distance = Speed × Time taken

Calculation:

Distance travelled by sachin in 4 hours = (4 × 40) = 160 km

Time taken by Tinku to cover same distance = 16 hours

Speed of Tinku = (160/16) = 10 km/hr

∴ The speed of Tinku is 10 km/hr
