In a two sector economy it is known that industry I uses 10 paise worth of its own product and 60 paise
worth of commodity II producer Rupee worth of commodity I, industry II uses 30 paise worth of its
own product and 50 paise worth of commodity I in producing a Rupee worth of commodityII and final
demands are Rs 1,100 billion worth of commodity I and Rs 2,200 billion worth of commodity II.
(i) write down the input output matrix for this economy
(ii) find the gross outputs of two industries to meet the final demand

A torsional pendulum consists of a horizontal disc of mass 100 kg suspended by a 4mm
diameter, 2m long vertical steel wire. Find the maximum angle of rotation (amplitude of
torsional vibration) so that the tensile stress in the wire does not exceed 100 N per sq.mm
and the maximum shear stress does not exceed 50 N per sq. mm. Take C= 80000 N per

Find using properties of determinants.
Can we do this like R1->R1+R2 and then take 5 common from R3 .So then R1 and R3 will become identical and hence the value of determinant will be 0. Is this right?
