Suppose the speed of Pratyush without flow is x km/h. And the speed of flow is y km/h.
Speed ​​of Pratyush with flow =(x+y) km/h
Speed ​​of the counter against the flow =(x−y) km/h
According to the question,

Solving equations (1) and (2), we get x = 7.5 km/h and y = 4 km/h.
The converted speed is x = 7.5 km/h and y  = (4−1.5) = 2.5 km/h.
The time taken to travel with the flow of 14 km = 14/(7.5+2.5) = 1.4 hours or 1 hour 24 minutes
∴ It takes 1 hour and 24 minutes for a person to travel 14 km with the flow in a changed landscape.

Taking their approximate value in the given expression:
? ≈ (1520/38) + (2/9) × 4050 − 125
To solve this question, follow the BODMAS rule,
? ≈ (1520/38) + (2/9) × 4050 − 125
⇒ ? = 40 + 900 − 125
∴ ? = 815

All others are divisible by 7 whereas 65 is not divisible by 7.

The series follows the following pattern:
(2 + 3)² + 1 = 25 + 1 = 26
(3 + 5)² + 1 = 64 + 1 = 65
(5 + 7)² + 1 = 144 + 1 = 145
(7 + 11)² + 1 = 324 + 1 = 325
(11 + 13)² + 1 = 576 + 1 = 577
∴ The required number in the series is 325.

To solve this question, follow the BODMAS rule,

We can write the given values as follows:

Given:
Number of white balls = 5 Number of red balls = 4
Concept used:
The probability of an event occurring is given by the number of favorable outcomes divided by the total number of possible outcomes.
Calculation:
Total number of balls = Number of white balls + Number of red balls
= 5 + 4 = 9
Number of favorable outcomes (drawing a ball that is not red) = Number of white balls
= 5
Probability = Number of favorable outcomes / Total number of possible outcomes
= 5 / 9
Therefore, the probability that the ball drawn is not red is 5/9.
The correct option is: 2) 5/9

Given:
X, Y and Z invested Rs. 4,000, Rs. 6,000 and Rs. 8,000 respectively in a business.
They invested the money for 3, 2 and 4 years respectively.
Total profit = Rs. 56000
Formula used:
Profit = Investment × Time Period
Calculation:
Profit of X = 4000 × 3 = Rs. 12000
Profit of Y = 6000 × 2 = Rs. 12000
Profit of Z = 8000 × 4 = Rs. 32000
∴ Y's share = [Y's profit/(X + Y + Z)'s profit] × 56000
∴ Y's share = [12000/56000] × 56000 = Rs. 12000
∴ Option 2 is the correct answer.

Given data:
Speed of boat in still water = 17 km/hr
Speed of stream = 11 km/hr
Concept: Upstream speed = Boat speed - Stream speed
Downstream speed = Boat speed + Stream speed
Solution:
⇒ Upstream speed = 17 - 11 = 6 km/hr
⇒ Downstream speed = 17 + 11 = 28 km/hr
⇒ Difference = Downstream speed - Upstream speed = 28 - 6 = 22 km/hr
Therefore, the difference between the upstream and downstream speed of the boat is 22 km/hr.

Drawing the diagram according to the given information,

The distance between the final and the initial point can be found by the Pythagoras theorem.
(Hypotenuse)² = (Base)² + (Perpendicular)².
(H)² = (60)² + (80)²
(H)² = 3600 + 6400
(H)² = 10000
H = 100m.
Therefore, the distance between his tutor's home from his home is "100m".
