According to the number line, Rita moves towards east is represented by a positive integer. But she moves in opposite direction means Rita moves west, is represented by negative integer. Distance from A to B = 20 km Distance from B to C = 30 km Distance from A to C = 20 – 30 = –10 km Thus, Rita is aRead more
According to the number line, Rita moves towards east is represented by a positive integer. But she moves in opposite direction means Rita moves west, is represented by negative integer.
Distance from A to B = 20 km
Distance from B to C = 30 km
Distance from A to C = 20 – 30 = –10 km
Thus, Rita is at final position from A to C is –10 km.
Deposit amount = ₹2,000 and Withdrawal amount = ₹1,642 ∴ Balance = 2,000 – 1,642 = ₹358 Thus, the balance in Mohan’s account after withdrawal is ₹ 358. 7 Maths Chapter 1 Exercise 1.1 Question 2, 3, 4, 5 & 6 for more answers vist to: https://www.tiwariacademy.com/ncert-solutions/class-7/maths/chaRead more

Height of a place above the sea level = 5000 m Floating a submarine below the sea level = 1200 m ∴ The vertical distance between the plane and the submarine = 5000 + 1200 = 6200 m Thus, the vertical distance between the plane and the submarine is 6200 m. 7 Maths Chapter 1 Exercise 1.1 Question 2, 3,Read more
Height of a place above the sea level = 5000 m
Floating a submarine below the sea level = 1200 m
∴ The vertical distance between the plane and the submarine
= 5000 + 1200 = 6200 m
Thus, the vertical distance between the plane and the submarine is 6200 m.
On Monday, temperature at Srinagar = –5°C On Tuesday, temperature dropped = 2°C ∴ Temperature on Tuesday = –5°C – 2°C = –7°C On Wednesday, temperature rose up = 4°C ∴ Temperature on Wednesday = –7°C + 4°C = –3°C Thus, temperature on Tuesday and Wednesday was –7°C and –3°C respectively. 7 Maths ChaptRead more
On Monday, temperature at Srinagar = –5°C
On Tuesday, temperature dropped = 2°C
∴ Temperature on Tuesday = –5°C – 2°C = –7°C
On Wednesday, temperature rose up = 4°C
∴ Temperature on Wednesday = –7°C + 4°C = –3°C
Thus, temperature on Tuesday and Wednesday was –7°C and –3°C respectively.

(a) The temperature of the places marked on it is: Places Temperature Bangalore 22°C Ooty 14°C Shimla 5°C Srinagar -2°C Lahulspiti -8°C (b) The temperature of the hottest place Bangalore = 22°C The temperature of the coldest place Lahulspiti = -8°C Difference = 22°C - (-8°C) = 22°C + 8°C = 30°C (c)Read more
(a) The temperature of the places marked on it is:
Places Temperature
Bangalore 22°C
Ooty 14°C
Shimla 5°C
Srinagar -2°C
Lahulspiti -8°C
(b) The temperature of the hottest place Bangalore = 22°C
The temperature of the coldest place Lahulspiti = -8°C
Difference = 22°C – (-8°C) = 22°C + 8°C = 30°C
(c) The temperature of Srinagar = -2°C
The temperature of Lahulspiti = -8°C
Difference = -2°C + (-8°C) = -2°C-8°C = 6°C
(d) The temperature of Srinagar and Shimla =5°C +(-2°) = 5°C-2°C = 3°C
The temperature at Shimla = 5°C
Therefore, 3°C -2°C
No, it is not less than the temperature at Srinagar.

A plane is flying at the height of 5000 m above the sea level. At a particular point, it is exactly above a submarine floating 1200 m below the sea level. What is the vertical distance between them?
Height of a place above the sea level = 5000 m Floating a submarine below the sea level = 1200 m ∴ The vertical distance between the plane and the submarine = 5000 + 1200 = 6200 m Thus, the vertical distance between the plane and the submarine is 6200 m. 7 Maths Chapter 1 Exercise 1.1 Question 2, 3,Read more

(a) The temperature of the places marked on it is:
Places Temperature
Bangalore 22°C
Ooty 14°C
Shimla 5°C
Srinagar -2°C
Lahulspiti -8°C
(b) The temperature of the hottest place Bangalore = 22°C
The temperature of the coldest place Lahulspiti = -8°C
Difference = 22°C – (-8°C) = 22°C + 8°C = 30°C
(c) The temperature of Srinagar = -2°C
The temperature of Lahulspiti = -8°C
Difference = -2°C + (-8°C) = -2°C-8°C = 6°C
(d) The temperature of Srinagar and Shimla =5°C +(-2°) = 5°C-2°C = 3°C
The temperature at Shimla = 5°C
Therefore, 3°C -2°C
No, it is not less than the temperature at Srinagar.
