Answer 1

Answer:

Mohan's score is 8 and Reshama's score is 15

Answer 2

Step-by-step explanation:

2.

20 km towards east = +20

30 km towards west = -30. (opposite direction)

final position from A = +20 -30 = -10 (which is 10 km toward west from A)

3.

Correct answer = +5 marks

incorrect answer = -2 marks

Mohan's marks

i) 4 correct answer = 4 × 5 = 20

6 incorrect answer = 6 × (-2) = -12

Total marks = 20 + (-12) = 20 -12 = 8 marks

Reshma's marks

ii) 5 correct answer = 5 × 5 = 25

5 incorrect answers = 5 × (-2) = -10

Total marks = 25 + (-10) = 25-10 = 15 marks

4.

Profit = Rs. 10 per white cement bag

Loss = Rs. 4 per grey cement bag

a) Company sells 3000 white cement bags

(profit = 3000 × 10 = 30000)

Company sells 5000 grey bags

(loss = 5000 × 4 = 20000)

Total profit = 30000 - 20000 = 10000

b) Let the number of white cement bags = x

x × 10 = 4000 × 4

10x = 16000

x = 16000/10

x = 1600
