1)

If the average price of a metre of cloth produced in the Handloom, powerloom and mill sectors is 2.5 : 1.5 : 1, then the percentage growth of the value of the cloth produced in 2004 - 05 over 2003 - 2004 was (assume no change in the relative price)


A) 12

B) 3

C) 16

D) cannot be determined

Answer:

Option B

Explanation:

The ratio of growth in handloom : powerloom : mill in 2004-05 over 2003-04 = 3137-2956 : 5445-5315 : 3432-3487 = 181 : 130 : -55

As there is a loss in mill,consider the handloom and power loom. So, ratio of growth percentage = $\frac{\frac{181}{2956}\times 100}{\frac{130}{5315}\times 100}$ 

\frac{\frac{181}{2956}\times 100}{\frac{130}{5315}\times 100}=\frac{6.12}{2.45}\approx \frac{2\times 3}{1\times 3}

There is approximately 3 percentage of growth in both handloom and powerloom.
