Correct Answer: 6 : 7

Solution : Let the cost price of the mobile phone as $x$. 
Given that a profit of 12% is made when the mobile phone is sold at Rs. P.
$P = x + 0.12x = 1.12x$
And there is a 4% loss when the phone is sold at Rs. Q.
$Q = x - 0.04x = 0.96x$
$\frac{Q}{P} = \frac{0.96x}{1.12x} = \frac{0.96}{1.12} = \frac{24}{28} = \frac{6}{7}$
Hence, the correct answer is 6 : 7.

Correct Answer: 3423

Solution : Given:
YOU is written as 7878 and GO is written as 108.

Multiply the positional value of letters and add 3 to the resultant of YOU, to obtain the required code –

(25 × 15 × 21) + 3 = 7878
Thus, YOU is coded as 7878
And in, Go is written as 108 –
G→7; O→15
(7 × 15) + 3 = 108
Similarly, follow the same pattern for SIT –
 S→19; I→9; T→20
(19 × 9 × 20) + 3 = 3423

So, SIT is coded as 3423. Hence, the first option is correct.
