Answer 2

• Given:- In 2004 for working class people wheat was selling at an average price of Rs. 16 per 20 kg, cloth at Rs. 2 per

meter, house rent Rs. 30 per house and other items at Rs. 10 per unit By 2005 cost of wheat rose by Rs. 4 per 20

Kg, house rent by Rs. 15 per house and other items doubled in price. The working class cost of living index for

the year 2005 (with 2004 as base) was 160.

• To find:- How much did cloth rose in price during the period.

• Solution:- According to the question

P01= 160

and For wheat P0= 16 , P1= (16+4=20)

for Clothes P0= 2, P1= 2+X

for house rent P0= 30, P1= 15

and For other items P0= 10 , P1=20

So, P01= =summation (P1/P0×100)]/n

or, 160= (200+50+125+50X+100)/4

or, X = 3.3

so, the cloth's price rose (3.3-2)=1.30
