Correct Answer: 21 years

Solution : The average age of Rustam and Preetam = 30 years
Use the formula to find the average, Average = $\frac{\text{Sum of the ages}}{{\text{Total number of Person}}}$
The sum of their ages = Average × Total number of Person = 2 × 30 = 60

Correct Answer: INR 3,000

Solution : Given, Discount = 12.5% and Selling price = 2625
Selling price = $\frac{100-\text{Discount}\%}{100}×\text{Marked price}$
⇒ $2625 = \frac{100-12.5}{100}×\text{Marked price}$
$\therefore$ Marked price $=\frac{100×2625}{87.5}=3000$
Hence, the correct answer is INR 3,000.

Correct Answer: 0°

Solution : Given, $\cos ^2 \theta-2+\cos \theta=0$
⇒ $\cos ^2 \theta+2\cos \theta-\cos\theta-2=0$
⇒ $\cos \theta(\cos \theta+2)-1(\cos \theta+2)=0$
⇒ $(\cos \theta+2)(cos \theta-1)=0$
⇒ $\cos \theta=-2$ or $\cos \theta=1$
Since the range of $\cos\theta$ is –1 < $\cos \theta$ < 1
Hence, $\cos\theta$ cannot be –2.
So, $\cos \theta=1⇒\theta=

Correct Answer: 10.5%

Solution : Let the cost price of goods be Rs.100
⇒ Marked price of goods $= 100 × \frac{130}{100} = \mathrm{Rs.}\ 130$
⇒ Selling price of goods $= 130 × \frac{100 - 15}{100} = \mathrm{Rs.}\ 110.5$
⇒ Profit % $= \frac{110.5 - 100}{100}×100 = 10.5\%$
Hence, the

Correct Answer: 40 kg

Solution : The total weight of 64 students with an average weight of 48 kg = 64 × 48 = 3072 kg
The total weight of 32 students with an average weight of 24 kg = 32 × 24 = 768 kg
The total weight of

Correct Answer: 270

Solution : Let's check the options –
First option: 306→(17)² + 17 = 289 + 17 = 306
Second option: 270→No such relation can be deduced. 
Third option: 132→(11)² + 11 = 121 + 11 = 132
Fourth option: 240→(15)² + 15 = 225
