Question : Direction: The pie chart shows the breakup of the monthly expenditure of a person.
If the expenditure incurred on clothes is Rs. 3,000. What is the expenditure incurred on education?
Option 1: Rs. 4,300
Option 2: Rs. 5,050
Option 3: Rs. 5,200
Option 4: Rs. 5,600
Correct Answer: Rs. 5,200
Solution : Expenditure incurred on cloth = Rs. 3,000 Given expenditure in percentage = 15% So, $\frac{15}{100}$ of Total expenditure = $3,000$ = 20,000 Total expenditure = Rs. 20,000 Expenditure on education = 26% of total expenditure = $\frac{26}{100}$ × 20000 = Rs. 5,200 Hence, the

Question : $\frac{4.41 × 0.16}{2.1 ×1.6 × 0.21}$ is simplified to:
Option 1: 1
Option 2: 0.1
Option 3: 0.01
Option 4: 10
Correct Answer: 1
Solution : Given: $\frac{4.41 × 0.16}{2.1 ×1.6 × 0.21}$ = $\frac{441 × 16 × 10 × 10 × 100 }{21 ×16 × 21 × 100 × 100}$ = $1$ Hence, the correct answer is 1.
Question : Select the most appropriate synonym of the given word.

The
Question : Directions: Select the letter cluster that can replace the question mark (?) in the given letter cluster series. XMT, ENA, LOH, SPO, ?
Option 1: YQU
Option 2: ZQZ
Option 3: YPC
Option 4: ZQV
Correct Answer: ZQV
Solution : Given: XMT, ENA, LOH, SPO, ?
In the above–given series, add 7 and 1 alternately to the letters of the previous term to obtain the next term. XMT→X + 7 = E; M + 1 = N; T + 7 = A ENA→E + 7
Question : A circular wire of length 168 cm is cut and bent in the form of a rectangle whose sides are in the ratio of 5 : 7. What is the length (in cm) of the diagonal of the rectangle?
Option 1: $\sqrt{4127}$
Option 2: $\sqrt{3137}$
Option 3: $\sqrt{1813}$
Option 4: $\sqrt{3626}$
Correct Answer: $\sqrt{3626}$
Solution : The length of the wire is equal to the perimeter of the rectangle. The sides of the rectangle are in the ratio 5 : 7. Let the sides be $5x$ cm and $7x$ cm. The perimeter of the rectangle $=2(5x + 7x) = 24x$ cm
Question : Ramu had to select a list of numbers between 1 and 1000 (including both), which are divisible by both 2 and 7. How many such numbers are there?
Option 1: 142
Option 2: 71
Option 3: 97
Option 4: 642
Correct Answer: 71
Solution : The numbers that are divisible by both 2 and 7 = 2 × 7 = 14 The smallest number divisible by 14 = 14 The largest number divisible by 14 = 994 (nearest to 1000) Let the required number be $n$. Now, $a_n=a+(n-1)d$, where $a_n$
Question : What is the LCM of 0.15, 0.18, and 0.45?
Option 1: 0.9
Option 2: 0.09
Option 3: 0.81
Option 4: 0.6
Correct Answer: 0.9
Solution : $0.15 = \frac{15}{100}$ $0.18 =\frac{18}{100}$ $0.45 =\frac{45}{100}$ We know, LCM of fractions = $\frac{\text{LCM of numerators}}{\text{HCF of denominators}}$ So, LCM of $ \frac{15}{100}, \frac{18}{100}$, and $\frac{45}{100}=\frac{90}{100}=0.9$ Hence the correct answer is 0.9.
