Answer

Question 4

The number 5,540,000,000,000 in the scientific notation can be written as:

(a) 554 × 10^{10}

(b) 55.4 × 10^{11}

(c) 5.54 × 10^{12}

(d) 5.54 × 10^{11}

Answer

5,540,000,000,000 = 5.54 × 10^{12} (c)

Question 5.

The number of unlike terms in the expression 5x^{2}y – 2xy^{2} – 2yx^{2} + 3y(xy + y^{2}) + 7 is

(a) 3

(b) 4

(c) 5

(d) 6

Answer

Number of unlike terms

5x^{2}y – 2xy^{2} – 2yx^{2} + 3y(xy + y^{2}) + 7

= 5x^{2}y – 2xy^{2} – 2yx^{2} + 3xy^{2} + 3y^{3} + 7

= 3x^{2}y + xy^{2} + 3y^{3} + 7 = 4 (b)

Question 6

x = -2 is a solution of the equation

(a) 2x + 5 = 9

(b) 3x – 1 = 5

(c) 4x + 3 = 1

(d) 5x + 12 = 2

Answer

5x + 12 = 5 × (-2) + 12 = -10 + 12 = 2 (d)

Question 7

Answer

**Section – B**

**Question numbers 9 to 14 are of 2 marks each.**

Question 9.

Using suitable properties, evaluate:

238 × (-44) + (-238) × 56.

Answer

238 × (-44) + (-238) × 56

= 238 × (-44) – (238) × 56

= 238 (-44 – 56)

= 238 × (-100)

= -23800

Question 10

State whether each of the following statement is true or false for the sets P and Q where P = {letters of TITLE} and Q = {letters of LITTLE}

(i) P ↔ Q

(ii) P = Q

Solution:

P = {letters of TITLE} = {T, I, L, E}

Q = {letters of LITTLE} = {L, I, T, E}

(i) P ↔ Q – True

(ii) P = Q – True

Question 11

Evaluate: -3 – (-2)

Answer

Question 14

If ₹ 4000 amounts to ₹ 5000 in 2 years, find the rate of simple interest per annum.

Solution:

Principal (P) = ₹ 4000

Amount (A) = ₹ 5000

S.I. = A – P = ₹ 5000 – ₹ 4000 = ₹ 1000

Time (T) = 2 years

Answer

Question 16

Vikram’s monthly salary is ₹ 12750. He spends of his salary on food and out of the remaining, he spends on rent and on the education of children. Find

(i) how much he spends on each item?

(ii) how much money is still left with him?

Answer

Monthly salary of Vikram = ₹ 12750

Spent on food = of 12750 = ₹ 2550

Remaining salary = ₹ 12750 – ₹ 2550 = ₹ 10200

Spent on rent = of ₹ 10200 = ₹ 2550

Spent on Education = × ₹ 10200 = ₹ 1700

Amount still left with him = ₹ 10200 – ₹ (2550 + 1700)

= ₹ 10200 – ₹ 4250

= ₹ 5950

Answer

Question 22

Solve the equation: 3(2x – 1) – 2(2 – 5x) = 1

Answer

3(2x – 1) – 2(2 – 5x) = 1

⇒ 6x – 3 – 4 + 10x = 1

⇒ 16x – 7 = 1

⇒ 16x = 1 + 7 = 8

⇒ x = =

Question 23

Answer

** Section -D**

**Question numbers 25 to 29 are of 6 marks each.**

Question 25.

If we represent the distance above the ground by a positive rational number and that below the ground by a negative rational number, then answer the following question:

An elevator descends into a mine shaft at the rate of 4 metre per minute. If it begins to descend from 7 metre above the ground, what will be its position after 18 minutes from the ground?

Answer

Speed of elevator into the mine = 4 = m/min

Time taken = 18 m

Total distance covered = × 18 = m = 85.5 m

Distance above the ground = 7.5 m

Distance below the ground = 85.7 – 7.5 = 78 m

It is below the ground.

It will be = -78 m
