Question : The following table shows the number of girls and boys in different classes. Find the sum of total number of students in all class.
Option 1: 840
Option 2: 842
Option 3: 800
Option 4: 760
Correct Answer: 842
Solution : Total girls = 88 + 140 + 54 + 84 + 90 = 456 Total boys = 76 + 92 + 80 + 68 + 70 = 386 Total students = Total girls + Total boys = 456 + 386 = 842 Hence, the correct
Question : If $x=\sqrt[3]{28}, y=\sqrt[3]{27}$, then the value of $x+y-\frac{1}{x^{2}+xy+y^{2}}$ is:
Option 1: 8
Option 2: 7
Option 3: 6
Option 4: 5
Correct Answer: 6
Solution : Given: $x=\sqrt[3]{28}$ and $y=\sqrt[3]{27}.$ To find $x+y–\frac{1}{x^{2}+xy+y^{2}}$ Multiplying and dividing by $(x–y)$ $=x+y–\frac{(x–y)}{(x–y)(x^{2}+xy+y^{2})}$ $=x+y–\frac{(x–y)}{(x^{3}–y^{3})}$ $=x+y–\frac{(x–y)}{(28–27)}$ $=x+y–x+y$ $=2y$ $=2×\sqrt[3]{27}$ $=2×3 = 6$ Thus, $x+y-\frac{1}{x^{2}+xy+y^{2}}=6$ Hence, the correct answer is 6.

Question : How many positive factors of 160 are there?
Option 1: 6
Option 2: 8
Option 3: 5
Option 4: 12
Correct Answer: 12
Solution : 160 = 25 × 5 If N = am × bn, where a and b are prime numbers, then the number of positive factors of N = (m+1) × (n+1) Total number of positive factors of 160 = 6 × 2
Question : Directions: Which of the following letter clusters will replace the question mark (?) in the given series? XG, UJ, RM, OP, ?
Option 1: MR
Option 2: LS
Option 3: MS
Option 4: LR
Correct Answer: LS
Solution : Given: XG, UJ, RM, OP, ?
In the above-given series, subtract 3 from the place value of the first letter and add 3 to the place value of the second letter. XG→X – 3 = U; G + 3 = J UJ→U – 3 =
Question : The presence of air bubbles in the bloodstream is dangerous to life because
Option 1: air combines with blood forming a complex

Option 2: Rs. 260
Option 3: Rs. 240
Option 4: Rs. 250
Correct Answer: Rs. 250
Solution : Let the labelled price be Rs. $x$ and the cost price be Rs. $y$. The shopkeeper sold the sarees at Rs. 266 each after giving a 5% discount on the labelled price. $x - 0.05x = 266$ $⇒0.95L = 266$ $⇒x = \frac{266}{0.95} =
