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

4.

In 1995, the export of Company A was double that of Company B. If the imports of Company A during the year was Rs. 180 crores, what was the approximate amount of imports pf Company B during that year?

Answer: Option

Explanation:

In 1995 for Company A we have:

E_{A} |
= 1.75 ... (i) |

I_{A} |

[where E_{A} = amount of exports, I_{A} = amount of imports of Company a in 1995]

In 1995 for Company B we have:

E_{B} |
= 0.75 ... (ii) |

I_{B} |

[where E_{B} = amount of exports, I_{B} = amount of imports of Company B in 1995]

Also, we have E_{A} = 2E_{B} ... (iii)

Substituting I_{A} = Rs. 180 crores (given) in (i), we get:

E_{A} = Rs. (180 x 1.75) crores = Rs. 315 crores.

Using E_{A} = Rs. 315 crores in (iii), we get:

E_{B} = |
E_{A} |
= Rs. | 315 | crores. | ||

2 | 2 |

Substituting E_{B} = Rs. |
315 | crores in (ii), we get: | ||

2 |

I_{B} = |
E_{B} |
= Rs. | 315 | crores = Rs. 210 crores. | ||

0.75 | 2 x 0.75 |

i.e., amount of imports of Company B in 1995 = Rs. 210 crores.

A= 175/100 & B=75/100.

180 * 175/100= 315/2 * 100/75 = 210.

180 * 175/100= 315/2 * 100/75 = 210.

In, 1995.

A -> E/I =1.25.

E=2x.

I=180.

B-> E/I=0.75.

E=x & I=?

E=(1.75 )I.

2x = 1.75 * 180

x = 157.5

I = 157.5 ÷ 0.75 = 210.

A -> E/I =1.25.

E=2x.

I=180.

B-> E/I=0.75.

E=x & I=?

E=(1.75 )I.

2x = 1.75 * 180

x = 157.5

I = 157.5 ÷ 0.75 = 210.
