Question : The basic unit of speed of an object is ______.
Option 1: metre per km (m/km)
Option 2: metre per hour (m/h)
Option 3: metre per second (m/s)
Option 4: metre per minute (m/m)
Correct Answer: metre per second (m/s)
Solution : The correct answer is meter per second (m/s).
Speed is the pace at which an object's position changes in any direction. The ratio of the object's distance travelled to its time travelled can be used to determine its speed. Since speed
Question : If $\frac{\sin x-\cos x}{\sin x+\cos x}=\frac{2}{5}$, then the value of $\frac{1+\cot ^2 x}{1-\cot ^2 x}$ is:
Option 1: 2.25
Option 2: 1.45
Option 3: 3.75
Option 4: 5.25
Correct Answer: 1.45
Solution : $\frac{\sin x-\cos x}{\sin x+\cos x}=\frac{2}{5}$ Dividing both the numerator and denominator by $\cos x$ ⇒ $\frac{1-\cot x}{1+\cot x}=\frac{2}{5}$ ⇒ $5-5\cot x=2+2\cot x$ ⇒ $\cot x=\frac{3}{7}$ So, $\frac{1+\cot ^2 x}{1-\cot ^2 x}$=$\frac{1+(\frac{3}7) ^2}{1-(\frac{3}7)^2 }=\frac{58}{40} = 1.45$ Hence, the correct answer is 1.45.
Question : What is the transplantation of graft between genetically identical individuals?
Option 1: Autograft
Option 2: Isograft
Option 3: Allograft
Option 4: Xenograft
Correct Answer: Isograft
Solution : The correct option is Isograft.
The transplantation of graft between genetically identical people is known as "isograft" or "isogeneic graft". The donor and recipient in this sort of grafting or transplantation have the same genetic composition because they are identical twins or clones. Because
Questions : '$a$' divides 228 leaving a remainder 18. The biggest two-digit value of '$a$' is:
Option 1: 70
Option 2: 21
Option 3: 35
Option 4: 30
Correct Answer: 70
Solution : Given: Number = 228, divisor = $a$, and remainder = 18 Subtract 18 from 228 = 210 Factors of 210 = 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, and 210 $\therefore$ The biggest two-digit value of $a$
Question : Directions: If P denotes +, Q denotes –, R denotes ÷, and S denotes ×, then 18 S 36 R 12 Q 6 P 7 = ?
Option 1: 115
Option 2: 65
Option 3: 55
Option 4: 25
Correct Answer: 55
Solution : Given: 18 S 36 R 12 Q 6 P 7 = ?
After replacing the letters with mathematical signs, the equation becomes – = 18 × 36 ÷ 12 – 6 + 7 = 18 × 3 – 6 + 7 = 54 – 6
