Q: Solve this inequality 3p - 16 < 20?

The given inequality is 3p - 16 3p < 36 Now divide the above eqn with 3 on both sides we get, 3p/3 < 36/3 p < 12.

Q: 10+10(9) =

According to BODMAS Rule, 10 + 10(9) = 10 + 90 = 100

Q: In an examination, a student scores 4 marks for every correct answer and loses I mark for every wrong answer. If he attempts in all 60 questions and secures 130 marks, the number of questions he attempts correctly, is:

Let the number of correct answers be X. Number of incorrect answers = (60 – X). Therefore, 4x – (60 – x) = 130 => 5x = 190 => x = 38

Question 1

Solve this inequality 3p - 16 < 20?

Accepted Answer

The given inequality is 3p - 16 < 20 For solving this inequality, follow these steps Now add 16 on both sides we get 3p - 16 + 16 < 20 + 16 => 3p < 36 Now divide the above eqn with 3 on both sides we get, 3p/3 < 36/3 p < 12.

Question 2

10+10(9) =

Accepted Answer

According to BODMAS Rule, 10 + 10(9) = 10 + 90 = 100

Question 3

In an examination, a student scores 4 marks for every correct answer and loses I mark for every wrong answer. If he attempts in all 60 questions and secures 130 marks, the number of questions he attempts correctly, is:

Accepted Answer

Let the number of correct answers be X. Number of incorrect answers = (60 – X). Therefore, 4x – (60 – x) = 130 => 5x = 190 => x = 38

Question 4

43% of 616.6 + 37% of 217 =?

Accepted Answer

43 x 616.6/100 + 37 x 217/100 => 265.138 + 80.29 => 345.428

Question 5

Simplify the following equation ? 2003 x 2004 - 2001 x 2002 = ?

Accepted Answer

(2000 + 3)(2000 + 4) - (2000 + 1)(2000 + 2) = ? Since (2000 x 2000) - (2000 x 2000) is equal to zero. ? = (8000 + 6000 + 12) - (4000 + 2000 + 2) => 14012 - 6002 = 8010.

Question 6

What is value of P+QP-Q if PQ=7 ?

Accepted Answer

h e n c e P = 7 Q P + Q P - Q = 7 Q + Q 7 Q - Q = 8 Q 6 Q = 4 3

Question 7

72 ÷ 52 × 3272 ÷ 52 of 32 ÷ 5.25

Accepted Answer

7 5 x 3 2 14 15 ÷ 525 100 9 4 ÷ 525 100 900 2100 = 3 7

Question 8

Simplify the following : 4 15 × 3 13 + ? = 20% of 120

Accepted Answer

Given equation can be written as 21 5 x 10 3 + ? = 24 = > 14 + ? = 24 = > ? = 24 - 14 = > ? = 10

Question 9

Simplify 39.96% of 649.85 ÷ 13.07 = 45.14 - ?

Accepted Answer

This can be easily simplified by Approximation process Given 39.96% of 649.85 ÷ 13.07 = 45.14 - ? can be written as 40% of 650 ÷ 13 = 45 - ? 40 x 650 100 13 = 45 - ? ? = 45 - 20 ? = 25 .

Question 10

In each question two equations numbered I and II are given,you haveto solve both the equation and choose the correctanswer. I. x2+ 30x + 81 = 0 II.y2-9y -162 = 0

Accepted Answer

x^2+ 30x + 81 = 0 x^2+ 27x + 3x + 81 = 0 x = -3, -27 y^2-9y -162 = 0 y^2-18y + 9y -162 = 0 y = -9, 18 Hence, no relationship can be established between x and y
