Question : If 4 men or 6 women can do a piece of work in 12 days, working 7 hours a day. How many days will it take to complete a work twice as large, with 10 men and 3 women working together 8 hours a day?
Option 1: 6 days
Option 2: 7 days
Option 3: 8 days
Option 4: 10 days
Correct Answer: 7 days
Solution : Given: 4 men or 6 women can do a piece of work in 12 days, working 7 hours a day. 4 men = 6 women, i.e. 2 men = 3 women So, 10 men and 3 women = 10 + 2 = 12 men
Question : Directions: Study the following histogram of wage distribution of different numbers of workers and answer the given questions. Total number of workers surveyed is:
Option 1: 44
Option 2: 40
Option 3: 49
Option 4: 39
Correct Answer: 49
Solution : The number of workers whose wages are between Rs. 900 to Rs. 910 is 3. The number of workers whose wages are between Rs. 910 to Rs. 920 is 2. The number of workers whose wages are between Rs. 920 to Rs. 930 is 4.
Question : The temperature, which has the same reading on both Fahrenheit and Celsius scales, is
Option 1: 40o
Option 2: -40o
Option 3: -34o
Option 4: -140o
Correct Answer: -40o
Solution : The correct option is -40o.
The temperature at which the Fahrenheit and Celsius scales have the same reading is -40o. This is the point where the numerical values are equal on both scales. Therefore, -40o Fahrenheit is equal
Question : Directions: DHJ is related to AEG in a certain way based on the English alphabetical order. In the same way, ZML is related to WJI. To which of the following is EKQ related following the same logic?
Option 1: HNT
Option 2: DJK
Option 3: BHN
Option 4: QKE
Correct Answer: BHN
Solution : Given: DHJ is related to AEG –
Subtract 3 from the place value of each letter of DHJ to obtain the required code – D – 3 = A; H – 3 = E; J – 3 = G Thus, DHJ is coded as AEG.
Question : If $\sec\theta +\tan\theta = 3$, then what is the value of $\sec \theta-\tan \theta$?
Option 1: $\frac{1}{3}$
Option 2: $6$
Option 3: $\frac{1}{6}$
Option 4: $\frac{1}{5}$
Correct Answer: $\frac{1}{3}$
Solution : Given, $\sec\theta +\tan\theta = 3$ We know that, $\sec^2θ−\tan^2θ=1$ ⇒ $(\secθ−\tanθ)(\secθ+\tanθ)=1$ ⇒ $(\secθ−\tanθ)(3)=1$ ⇒ $\secθ-\tanθ=\frac13$ Hence, the correct answer is $\frac{1}{3}$.
