Answer»

Let Airtel had invested Rs. x THOUSAND crores for seven months.

Ratio of time invested by Nokia to Airtel = 12 ? 7.

Ratio of MONEY invested by Nokia to Airtel = 735 ? x

Ratio of REVENUES = $(\frac{{12 \TIMES 735}}{{7 \times x}} = \frac{7}{5})$

$(\Rightarrow x = \frac{{12 \times 735 \times 5}}{{7 \times 7}} = 12 \times 15 \times 5 = 900)$

AMOUNT contributed by Airtel = Rs. 900 thousand crores
