Correct Answer: 4 : 5 : 11

Solution : P invests $\frac{1}{5}$th of the total investment.
Q invests $\frac{1}{4}$th of the total investment.
Taking, LCM (4, 5) = 20
Let the total investment be Rs. 20
P invests $\frac{1}{5}$th of the total investment = $\frac{1}{5}\times 20$ = Rs. 4
Q invests $\frac{1}{4}$th of the total investment = $\frac{1}{4}\times 20$ = Rs. 5
Thus R invests = Rs. 20 – (Rs. 4 + Rs. 5) = Rs. 20 – Rs. 9 = Rs. 11
Thus the ratio of the profit of P, Q, and R respectively is 4 : 5 : 11.
Hence, the correct answer is 4 : 5 : 11.

Correct Answer: Sodium

Sodium is an element with a higher atomic number than fluorine. Sodium has an atomic number of 11 and Fluorine's atomic number is 9. 

Correct Answer: 100 km

Solution : Speed of train = 50 km/hr
Speed of walking = 10 km/hr
Total time for journey = 12 hours
Let the distance to be covered be $d$ km.
Time taken by train = $\frac{d}{50}$
Time taken by walking = $\frac{d}{10}$
According to the question :
$⇒ \frac{d}{50} + \frac{d}{10} = 12$
$⇒ 6d = 50 × 12$
$⇒ d = 100$ km
Hence, the distance travelled by train is 100 km.
Hence, the correct answer is 100 km.

Correct Answer: BBDE

Solution : Given:
VVXY : RRTU :: FFHI : ?

Subtract 4 from the place value of each letter of VVXY to obtain the required code –
V – 4 = R; V – 4 = R; X – 4 = T; Y – 4 = U
Thus, VVXY is coded as RRTU.
Similarly, follow the same pattern for FFHI –
F – 4 = B; F – 4 = B; H – 4 = D; I – 4 = E

Thus, FFHI is coded as BBDE. Hence, the fourth option is correct.
