Question : A sum of Rs. 5,000 is divided into two parts such that the simple interest on the first part for $4 \frac{1}{5}$ years at $6 \frac{2}{3} \%$ p.a. is double the simple interest on the second part for $2 \frac{3}{4}$ years at 4% p.a. The ratio of the second part to the first part is:
Option 1: 11:14
Option 2: 11 : 13
Option 3: 14 : 11
Option 4: 13 : 11
Correct Answer: 14 : 11
Solution : Let the first part of the sum as $x$ and the second part as $5000 - x$. Given that the simple interest on the first part is double the simple interest on the second part. $x \times \frac{21}{5} \times \frac{20}{3} \% = 2

Question : What is the volume of the largest sphere that can be carved out of a wooden cube of sides 21 cm?$\left(\pi=\frac{22}{7}\right)$
Option 1: 3851 cm3
Option 2: 6858 cm3
Option 3: 4851 cm3
Option 4: 5821 cm3
Correct Answer: 4851 cm3
Solution : The largest sphere that can be carved out of a cube of side 21 cm will have a diameter of 21 cm. So, the radius of the sphere, $r$ = $\frac{21}{2}$ cm Now the volume of the sphere = $\frac{4}{3}\pi r^3$ = $\frac{4}{3}×\frac{22}{7}×\frac{21}{2}×\frac{21}{2}×\frac{21}{2}$

Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following set. (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.) (26, 14, 170) (31, 7, 18)
Option 1: (11, 5, 17)
Option 2: (34, 10, 72)
Option 3: (21, 9, 60)
Option 4: (14, 6, 24)
Correct Answer: (21, 9, 60)
Solution : Given: (26, 14, 170); (31, 7, 18)
In the given sets, add the first and the third numbers. The resultant is the square of the second number. (26, 14, 170)→26 + 170 = 196; (14)2 = 196 (31, 7, 18)→31 + 18
Question : Direction: If NOTE is written as PQVG, then TIME is written as?
Option 1: VQOG
Option 2: VKOG
Option 3: VOKG
Option 4: VGKO
Correct Answer: VKOG
Solution : Given: NOTE is coded as PQVG: N + 2 = P ; O + 2 = Q ; T + 2 = V ; E + 2 = G
Similarly, TIME will be coded as: T + 2 = V ; I + 2 =
Question : If $5A=12B=13C$, then find $A: B: C$.
Option 1: $60:65:156$
Option 2: $65:156:60$
Option 3: $156:65:60$
Option 4: $3:12:5$
Correct Answer: $156:65:60$
Solution : Given: $5A=12B=13C$ Let $5A=12B=13C=k$ $⇒A=\frac{k}{5},B=\frac{k}{12},C=\frac{k}{13}$ Ratio of $A:B:C=\frac{k}{5}:\frac{k}{12}:\frac{k}{13}$ $⇒A:B:C=\frac{1}{5}:\frac{1}{12}:\frac{1}{13}$ LCM of $(5, 12, 13) = 780$ Multiplying with it, we get, $⇒A:B:C=\frac{780}{5}:\frac{780}{12}:\frac{780}{13}$ $\therefore A : B : C = 156:65:60$ Hence, the correct answer is $156:65:60$.
