Question : The pie chart given below shows the number of cars sold by 8 different companies. The total number of cars sold by all these 8 companies is 2,000. The number of cars sold by a particular company is shown as a percent of the total number of cars sold by all these 8 companies.
The average number of cars sold by C1 and C2 is how much percent less than the average number of cars sold by C7 and C8?
Option 1: 66.66%
Option 2: 33.33%
Option 3: 16.66%
Option 4: 25%
Correct Answer: 25%
Solution : The average number of cars sold by C1 and C2 = $\frac{8+22}{2}=15$%. The average number of cars sold by C7 and C8 = $\frac{10+30}{2}=20$%. The average number of cars sold by C1 and C2 is less than the average number of cars sold by C7
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) (4, 21, 33) (10, 111, 141)
Option 1: (13, 45, 97)
Option 2: (25, 53, 128)
Option 3: (65, 60, 244)
Option 4: (24, 52, 128)
Correct Answer: (25, 53, 128)
Solution : Given: (4, 21, 33); (10, 111, 141) ⇒ (4, 21, 33); 33 – 21 = 12; 12 ÷ 3 = 4 ⇒ (10, 111, 141); 141 – 111 = 30; 30 ÷ 3 = 10
Let's check the options – First option: (13,
Question : Directions: In the following question, four number pairs are, given. In each pair, the number on the left side of (–) is related to the number on the right side of (–) with some Logic/Rule /Relation. Three pairs are similar based on the same Logic/Rule/Relation. Select the odd one out from the given alternatives. (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)
Option 1: 14 – 2762
Option 2: 16 – 4098
Option 3: 11 – 1333
Option 4: 13 – 2199
Correct Answer: 14 – 2762
Solution : Let's check each option –
First option: (14 – 2762); 143 + 2 = 2744 + 2 = 2746 ≠ 2762 Second option: (16 – 4098); 163 + 2 = 4096 + 2 = 4098 Third option: (11 – 1333); 11
Question : At how much percent above the cost price should a trader mark his goods so that after allowing a discount of 25%, he still gains 5%?
Option 1: 35
Option 2: 32
Option 3: 50
Option 4: 40
Correct Answer: 40
Solution : Let the cost price be Rs. $100$. So, the selling price is $100 + 5$ = Rs. $105$ Discount is $25$%. Let, the marked price be $x$. So, the selling price after the discount is $\frac{75}{100}×x=\frac{3x}{4}$ According to the question, $\frac{3x}{4} = 105$ $\therefore x
Question : Directions: Two statements are given followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: All teas are juices. All juices are cocktails. Conclusions: I. All teas are cocktails. II. All cocktails are definitely juices.
Option 1: Both conclusions I and II follow
Option 2: Only conclusion II follows
Option 3: Only conclusion I follows
Option 4: Neither conclusion I nor II follows
Correct Answer: Only conclusion I follows
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): All teas are cocktails – From the Venn diagram, it is evident that the circle representing tea is completely inside the circle

Question : Directions: In a certain code language, ENJOY is coded as 25, and DOCTOR is coded as 36. How will MILLION be coded in that language?
Option 1: 39
Option 2: 49
Option 3: 51
Option 4: 64
Correct Answer: 49
Solution : Given: ENJOY is coded as 25, and DOCTOR is coded as 36.
Count the number of the alphabet of the given word and the resultant is squared to obtain the required code. ENJOY→Number of alphabets→5; (5)2 = 25 DOCTOR→Number of alphabets→6; (6)2 =
Question : If $\frac{x^2+1}{x}=5$, then find the value of $x^4+\frac{1}{x^4}-36$.
Option 1: 491
Option 2: 149
Option 3: 419
Option 4: 194
Correct Answer: 491
Solution : $\frac{x^2+1}{x}=5$ ⇒ $x+\frac{1}{x}=5$ Squaring both sides, we get, ⇒ $x^2+\frac{1}{x^2}+2=25$ ⇒ $x^2+\frac{1}{x^2}=23$ Squaring both sides, we get, ⇒ $x^4+\frac{1}{x^4}+2=529$ Subtracting 38 from both sides. ⇒ $x^4+\frac{1}{x^4}-36 =491$ Hence, the correct answer is 491.
Question : Which one of the following is used as secondary storage system in computer ?
Option 1: RAM
Option 2: Floppy
Option 3: EPROM
Option 4: ROM
Correct Answer: Floppy
Solution : The correct option is floppy.
In early computer systems, floppy discs were employed as secondary storage. They were compact, portable storage media with a limited capacity, often ranging from 360 kilobytes (KB) to 1.44 megabytes (MB). Floppy discs, on the other hand, are now mostly
