Solution

From the line-graph it is clear that the productions of Company X in the years 1997, 1998, 1999, 2000, 2001 and 2002 are 119000, 99000, 141000, 78000, 120000 and 159000 and those of Company Y are 139000, 120000,100000, 128000, 107000 and 148000 respectively.

Total production of Company X from 1997 to 2002.

= 119000 + 99000 + 141000 + 78000 + 120000 + 159000 = 716000.

Hence, the correct option is (c).

and total production of Company Y from 1997 to 2002

= 139000 + 120000 + 100000 + 128000 + 107000 + 148000

= 742000.

Difference = (742000 - 716000) = 26000.

...view full instructions

If the imports in 1998 were Rs.250 crores and the total exports in the years 1998 and 1999 together was Rs.500 crores, then the imports in 1999 was?

A
Rs.250 crores

B
Rs.300 crores

C
Rs.357 crores

D
Rs.357 crores

Solution

The ratio of imports to exports for the years 1998 and 1999 are 1.25 and 1.40 respectively.

Let the exports in the year 1998 = Rs. x crores.

Then, the exports in the year 1999 = Rs.(500 - x) crores.

1.25 = $\frac{250}{x}$ $\Rightarrow$ x = $\frac{250}{1.25}$ = 200 ( Using ratio for 1998

Thus, the exports in the year 1999 = Rs.(500 - 200) crores = Rs.300 crores.

Let the imports in the year 1999 = Rs. y crores.

Then, 1.40 = $\frac{y}{300}$ $\Rightarrow$ y = ( 300 $\times$ 1.40 ) = 420

Imports in the year 1999 = Rs.420 crores.

Hence, the correct option is (d).
