Question : A businessman's earnings increased by 25% in one year but decreased by 4% in the next. Going by this pattern, after 5 years, his total earnings would be Rs. 72,000. What is his present income?
Option 1: Rs. 10,000
Option 2: Rs. 80,000
Option 3: Rs. 40,000
Option 4: Rs. 54,000
Correct Answer: Rs. 40,000
Solution : Let the present income be Rs. $x$ According to the question, $x × 1.25 × 0.96 × 1.25 × 0.96 × 1.25 = 72000$ ⇒ $x = \frac{72000}{1.25 × 0.96 × 1.25 × 0.96 × 1.25}$ ⇒ $x = \frac{72000}{1.2 × 1.2 × 1.25}$

Question : Directions: In the following question, some parts of the sentence have errors, and some are correct. Find out which part of the sentence has an error. The number of that part is the answer. If a sentence is error-free, your answer is "No Error".
A study is going underway to determine the exact concentration of lead in the water supply.
(1) to determine the exact concentration
(2) No Error
(3) of lead in the water supply
(4) A study is going underway
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 4
Correct Answer: 4
Solution : The phrase "is going underway" is redundant because "underway" already means "in progress" or "being carried out." Therefore, it is not necessary to use both "going" and "underway" together. The corrected sentence is, "A study is underway to determine the exact concentration of lead in
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.) (60, 17, 13) (62, 14, 17)
Option 1: (56, 15, 13)
Option 2: (43, 9, 12)
Option 3: (55, 18, 9)
Option 4: (57, 15, 14)
Correct Answer: (56, 15, 13)
Solution : Given: (60, 17, 13); (62, 14, 17)
Add the second and third numbers and the sum is multiplied by 2 to obtain the first number in the given set of numbers – ⇒ (60, 17, 13)→17 + 13 = 30 × 2 =
Question : Directions: If A denotes +, B denotes ×, C denotes −, and D denotes ÷, then what will be the value of the following expression? 67 C 45 A 12 D 6 B 2 = ?
Option 1: 23
Option 2: 22
Option 3: 26
Option 4: 24
Correct Answer: 26
Solution : Given: 67 C 45 A 12 D 6 B 2 = ?
On replacing the letters with the mathematical signs, the equation becomes – = 67 – 45 + 12 ÷ 6 × 2 = 67 – 45 + 2 × 2 = 67 –
Question : The radius of a circle is increased by 20%. Find the percentage increase in the circumference of the circle.
Option 1: 30%
Option 2: 20%
Option 3: 15%
Option 4: 40%
Correct Answer: 20%
Solution : Let the original radius be $r$. New radius $=r+\frac{20}{100} \times =1.2r$ Old circumference $=2\pi r$ New circumference $=2 \pi \times 1.2r=2.4\pi r$ Increase in circumference $=2.4\pi r - 2 \pi r=0.4\pi r$ $\therefore$ Percentage increase in circumference $=\frac{0.4 \pi r}{2\pi r} \times 10=20\%$ Hence, the
Question : The base of a right pyramid is an equilateral triangle with a side of 8 cm, and its height is $30 \sqrt{3}$ cm. The volume (in cm$^3$ ) of the pyramid is:
Option 1: $240 \sqrt{3}$
Option 2: $360 \sqrt{3}$
Option 3: $480$
Option 4: $360$
Correct Answer: $480$
Solution : Volume of pyramid = $\frac{1}{3}$ × area of base × height = $\frac{1}{3}$ × area of equilateral triangle × height = $\frac{1}{3}×\frac{\sqrt3}{4}$ × (8)2 × $30 \sqrt{3}$ = $\frac{\sqrt3}{4}$ ×64 = 480 cm3 Hence, the correct answer is $480$.
