Option 1: KR
Option 2: RK
Option 3: LR
Option 4: LK
Correct Answer: RK

Question : If $b=5$, determine the value of an expression $\left(\frac{5}{b}+5b\right)\left(\frac{25}{b^{2}}-25+25 b^2\right)$ using an identity.
Option 1: 25,726
Option 2: 15,626
Option 3: 15,438
Option 4: 25,636
Correct Answer: 15,626
Solution : $(\frac{5}{b}+5 b)(\frac{25}{b^{2}}-25+25 b^2)$ This equation is in the form of $(x+y)(x^{2}–xy+y^{2})$ We know $x^{3}+y^{3}=(x+y)(x^{2}–xy+y^{2})$ So, $x = \frac{5}{b}$ and $y = 5b$ Putting the value of $b = 5$ we get, $x^{3}+y^{3} = (\frac{5}{5})^{3} + (5\times 5)^{3}$ Or, $x^{3}+y^{3}= 1+15625 = 15626$ Hence, the correct

Option 2: Rs. 22,440
Option 3: Rs. 20,000
Option 4: Rs. 25,000
Correct Answer: Rs. 22,440
Solution : The price of a mobile is Rs. 30,000. The value of the mobile depreciates by 12% at the end of the first year. Price of the mobile after 1 year = $\frac{88}{100}×30000=26400$ The value of the mobile depreciates by 15% at the end of

Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 - operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed.) (82, 35, 78) (18, 27, 30)
Option 1: (21, 27, 24)
Option 2: (15, 36, 38)
Option 3: (27, 33, 40)
Option 4: (20, 25, 32)
Correct Answer: (27, 33, 40)
Solution : Given: (82, 35, 78); (18, 27, 30)

Question : Two numbers are in the ratio 7 : 11. If their HCF is 28, then the difference between the two numbers is:
Option 1: 28
Option 2: 308
Option 3: 112
Option 4: 196
Correct Answer: 112
Solution : Ratio of two numbers = 7 : 11 HCF = 28 Let the numbers be $7x$ and $11x$. HCF of $7x$ and $11x=x$ ⇒ $x= 28$ Difference $=11x-7x=4x= 4 × 28= 112$ Hence, the correct answer is 112.
