Correct Answer: 3 hours

Solution : Let the time of driving at 40 km/hr be $t$ hours.
The total distance travelled = $( 50 \times 2 + 40 \times t)$ km
The total time of travelling = $2 + t$ hours.
According to the question,
⇒ $44 = \frac{{50 \times

Correct Answer: 2197

Solution : Given:
441 : 9261 :: 169 : ?

Multiply the first number by its square root to obtain the second number.
Here, 441 : 9261→441 × $\sqrt{441}$ = 441 × 21 = 9261
Similarly, follow the same pattern for 169 –
169 × $\sqrt{169}$ =

Correct Answer: 90 days

Solution : Let's the rate of work for U, V, and W are U, V, and W, respectively.
It is given that
U = 3V and V = 2W
⇒ U = 6W
According to the question,
Total Work = (U + V + W) ×

Correct Answer: Chlorine

Correct Answer: 7%

Solution : Given,
Loan amount = Rs 700
Interest amount = Rs 343
We know, Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$
According to the question,
Time of interest = Rate of interest
⇒ Simple interest = $\frac{700×\text{Rate × Time}}{100}$
⇒ 343 = 7 × Rate

Correct Answer: 3

Solution : Given: $\frac{39}{25} \div \frac{13}{5}+\frac{33}{5} \times \frac{4}{11}$
= $\frac{39}{25} \times \frac{5}{13}+\frac{33}{5} \times \frac{4}{11}$
= $\frac{3}{5}+\frac{12}{5}$
= $\frac{3+12}{5}$
= $\frac{15}{5}$
= $3$
Hence, the correct answer is 3.

Correct Answer: 1024

Solution : The correct option is 1024.
