Find MPC, MPS, APC and APS , if the expenditure `E_c` of a person with income I is given as `E_( c) = (0.0003)I^(2) + (0.075)I`, when I = 1000

find consumption expenditure from the following : National income =Rs. 5,000 Autonomous consumption = Rs, 1,000 MPC = 0.80

If A^(2)-A+ I =0 then the inverse of A is - (a) I-A (b) A-I (c) A (d) A+I

Monochromatic light of wavelength 5000 Å is used in Y.D.S.E., with slit-width, d = 1mm, distance between screen and slits, D = 1m. If intensity at the two slits are I_(1)=4I_(0), I_(2)=I_(0) , find Distance of the 1000^(th) maxima

(i) The disposable income (Y) is ₹ 1200 crores and consumption expenditure ( C) is ₹ 800 crores. Calculate the APC. If saving is ₹ 500, out of an income of ₹ 5,000, how much is the APS ? (iii) If disposable income is ₹ 1,000 and consumption expenditure is ₹ 750, find out average propensity to save. (iv) If income is ₹ 100, calculate APC. (v) When incomes rises from ₹ 1,000 to ₹ 1,100, saving rise by ₹ 30. Find out MPS and MPC.

If A^(2)-A+I=0, then the inverse of A is: (A) A+I (B) A(C)A-I (D) I-A

Calculate the value of multiplier, if MPC is (i) 0.60, (ii) 0.50

In figure i_(1) = 10 e^(-2t) A, i_(2) = 4 A, v_(C ) = 3 e^(-2t) V The current i_(L) is

If a, b, c, d, e be 5 numbers such that a, b, c are in AP, b, c, d, are in GP & c, d, e are in HP then (i) Prove that a,c,e are in GP. (ii) Prove that e=(2b-a)^2//a . (iii) If a=2& e=18 , find all possible vlaues of b,c,d.
