Ratio of Exports to Imports (in terms of money in Rs. crores) of Two Companies Over the Years

2.
If the imports of Company A in 1997 were increased by 40 percent, what would be the ratio of exports to the increased imports?
1.20
1.25
1.30
cannot be determined
Explanation:

In 1997 for Company A we have:

 E = 1.75     i.e.,     E = 1.75I I

where E amount of exports, I = amount of imports of Company A in 1997.

Now, the required imports I1 = I + 40% of I = 1.4I.

 Required ratio = E = 1.75I = 1.25. I1 1.4I

1.4i get from that it increase by 40% , so 100%+40% = 140 % = 1.4.

So we say that (new import = 1.4 old import).

Here it is:
40% of I is 40/100 of I=40I/100.
Now 40 increase to I=I+40I/100.
=(100I +40I)/100,
=140I/100.
=1.4I.

40 percent of Import can be calculated as 40 percent of I which becomes = 0.40 I.

Now add this 0.40 I to I i.e 1 I. It can be written as 1 I + 0.40 I = 1.40 I or any zero on right side of any digit after decimal can be ignored and this can be written as 1.4 I.
