Question : In a right-angled triangle PQR, right-angled at Q, the length of the side PR is 17 units, the length of the base QR is 8 units, and the length of the side PQ is 15 units. If $\angle RPQ = \sin\alpha $, then $\sin\alpha + \cos\alpha$ is:
Option 1: $\frac{18}{17}$
Option 2: $\frac{23}{17}$
Option 3: $\frac{21}{17}$
Option 4: $\frac{15}{17}$
Correct Answer: $\frac{23}{17}$
Solution : Given, triangle PQR is right-angled at Q with $\angle$RPQ = $\alpha$ PR is 17 units, QR = 8 units, and PQ = 15 units $\sin\alpha+\cos\alpha$ = $\frac{\text{QR}}{\text{PR}}+\frac{\text{PQ}}{\text{PR}}$ = $\frac{8}{17}+\frac{15}{17}$ = $\frac{23}{17}$ Hence, the correct answer is $\frac{23}{17}$.

Question : The given chart shows the marks scored by a class X student in different subjects. If the total marks are 1800, then find the difference between the marks scored in science and mathematics.
Option 1: 2
Option 2: 10
Option 3: 1
Option 4: 5
Correct Answer: 10
Solution : As per the given graph, The total mark is 1800. The total degree of marks = 360° The total marks scored in Science = $\frac{82^\circ}{360^\circ}$ × 1800 = 410 The total marks scored in Mathematics = $\frac{84^\circ}{360^\circ}$ × 1800 = 420 $\therefore$ The required difference
Question : Direction: Study the bar diagram and answer the following question. The bar diagram shows the number of bicycles parked in the parking space of a hall at various points in time.
How many times, as mentioned in the graph, is the number of parked cycles above average?
Option 1: 3
Option 2: 4
Option 3: 5
Option 4: 6
Correct Answer: 6
Solution : The number of cycles = 95 + 75 + 85 + 65 + 75 + 55 + 65 + 45 + 55 + 35 + 45 + 25 = 720. Total time = 12 hours The average number of cycles parked = $\frac{\text {Total number
