• Questions 6-8 carry 3 marks each
• Questions 9-10 carry 4 marks each.

Choose the correct answer from the given four options (1-2):

#### Question 1.

(-10) × 2 + 0 ÷ (-2) is equal to
(a) -20
(b) 20
(c) -22
(d) 22

(-10) × 2 + 0 – (-2) = -20 + 0 = -20 (a)

Question 2.

The sum of a rational number $\frac { -1 }{ 2 }$ and its multiplicative inverse is
(a) 0
(b) 1
(c) -2 $\frac { 1 }{ 2 }$
(d) -2

Sum of $\frac { -1 }{ 2 }$ and its multiplication inverse $\frac { -1 }{ 2 }$ + $\frac { -2 }{ 1 }$ $\frac { -5 }{ 2 }$
= -2 $\frac { 1 }{ 2 }$ (c)

#### Question 3.

Evaluate: (-36) ÷ ((-14) + 2).

(-36) ÷ (-14 + 2)
(-36) ÷ (-12) = 3

Question 4.

If the length of a rectangle is 8.26 cm and its breadth is 5.5 cm, then find the area of the rectangle.

Length of a rectangle = 8.26 cm
= 8.26 × 5.5 sq cm
= 45.430
= 45.43 sq cm

#### Question 5.

Reduce the rational number $\frac { 105 }{ -168 }$ standard form. $\frac { 105 }{ -168 }$
LCM of 105 and 168 = 21 $\frac { 105\div \left( -21 \right) }{ -168\div \left( -21 \right) } =\frac { -5 }{ 8 }$

#### Question 6.

In a competition, the question paper consists of 20 questions. 5 marks are awarded for every correct answer and 2 marks are deducted for every incorrect answer and 0 marks for every question not attempted. Vishal attempted 17 questions and got 11 correct answers. What is his score?

Number of total questions = 20
Award for a correct answer = 5
and deduction for incorrect answer = 2
Marks for not attempting of a question = 0
Vishal attempted 17 questions and got 11 correct answers
His total award = 11 × 5 – (17- 11) × 2 + 3 × 0
= 55 – 6 × 2 + 0
= 55 – 12 + 0
= 43 marks

#### Question 7.

Barkha bought 20 $\frac { 3 }{ 8 }$ kg rice at the rate of ₹ 17 $\frac { 1 }{ 2 }$ per kg and sent it to an orphanage. Find the amount spent by Barkha. What value is being promoted? #### Question 8.

Which rational number is greater -5 $\frac { 5 }{ 9 }$ or -5 $\frac { 7 }{ 12 }$ ?

Which rational is greater #### Question 9.

Simran walks 1 $\frac { 5 }{ 12 }$ km from a place A towards north and then from there she walks 2 $\frac { 7 }{ 9 }$ km towards south. Where will be she now from place A?

From A, Simran walks, 1 $\frac { 5 }{ 12 }$ km towoards north
and then towards 2 $\frac { 7 }{ 9 }$ km towards south. #### Question 10.

If the product of two decimal numbers is 17.55 and one of them is 2.7, then find the other.

#### Solution

Product of two decimal numbers = 17.55
One number = 2.7
Second number = 17.55 ÷ 2.7 $\frac { 1755 }{ 270 }$
= 6.5 – : End of Model Question Paper-1 Solved Class-7 ML Aggarwal Solutions  :–
