Question : Study the bar graph and answer the question. The total number of trees planted in state B in 2015 and 2017 was what percentage less than the total number of trees planted in state A in 2014, 2016, and 2017? (Your answer should be correct to one decimal place.)
Option 1: 19.8%
Option 2: 21.4%
Option 3: 20.8%
Option 4: 20.1%
Correct Answer: 20.8%
Solution : The total number of trees planted in state B in 2015 and 2017 = 118 + 72 = 190 The total number of trees planted in state A in 2014, 2016, and 2017 = 70 + 78 + 92 = 240 The required percentage $=\frac{240–190}{240}\times
Question : The highest common factor of 108, 72, and 5$a$ is $a$. What can be the least common multiple of 108, 72, and $a$?
Option 1: 432
Option 2: 324
Option 3: 108
Option 4: 216
Correct Answer: 216
Solution : The highest common factor (HCF) of 108, 72, and 5$a$ is given as $a$. This means $a$ is a factor of 108, 72, and 5$a$. Since '$a$' is a factor of 108 and 72, then $a$ must be a divisor of the HCF of 108
Question : In finding the HCF of two numbers by division method, the quotients are 1, 8 and 2 respectively, and the last divisor is 105. What is the sum of the numbers?
Option 1: 3570
Option 2: 3885
Option 3: 3780
Option 4: 3675
Correct Answer: 3780
Solution : Last divisor = 105 and quotient = 2 Dividend (c) = 105 × 2 = 210 Now, divisor = 210, quotient = 8 and remainder = 105 So, dividend (a) = 210 × 8 + 105 = 1785 Again, divisor = 1785, quotient = 1
Question : Directions: If + means –, – means ×, × means ÷, ÷ means +, then what will come in place of the question mark (?) in the following equation? 61 ÷ 9 × 3 – 8 + 5 = ?
Option 1: 80
Option 2: 75
Option 3: 89
Option 4: 72
Correct Answer: 80
Solution : Given: + means –, – means ×, × means ÷, ÷ means + 61 ÷ 9 × 3 – 8 + 5 = ?
After interchanging the given mathematical signs, we get – ⇒ 61 + 9 ÷ 3 × 8 – 5 ⇒ 61
Question : Solve the following expression. $456-\left(76+15^2\right)+\frac{3}{4} \text { of } \frac{76}{18} \div\left(\frac{19}{72 \times 24}\right)$
Option 1: 443
Option 2: 256
Option 3: 356
Option 4: 401
Correct Answer: 443
Solution : $456-\left(76+15^2\right)+\frac{3}{4} \text { of } \frac{76}{18} \div\left(\frac{19}{72 \times 24}\right)$ $=456-\left(76+15^2\right)+(\frac{3}{4} \times \frac{76}{18}) \div\left(\frac{19}{72 \times 24}\right)$ $=456-\left(76+15^2\right)+\frac{19}{6} \times \frac{72×24}{19}$ $=456-\left(76+225\right)+12 \times24$ $=456-301+288$ $=443$ Hence, the correct answer is 443.
Question : Study the given pie chart and answer the question that follows. Break up (degree-wise) the number of students in five schools (A, B, C, D, and E) in a city. Total number of students = 5200
If the total number of students in schools D and E exceeds the number of students in school A by x, then x lies between:
Option 1: 500 and 525
Option 2: 475 and 500
Option 3: 525 and 550
Option 4: 550 and 575
Correct Answer: 500 and 525
Solution : According to the question Number of students in schools D and E = 64.8º + 57.6º = 122.4º School A = 86.4º Now, ⇒ Number of students in D and E = $\frac{\text{Number of student in schools D and E}}{360º }$ = $\frac{122.4º
