101) Sum of greatest 5-digit number and smallest 5-digit number formed by the digits 6, 3, 0, 2 and 8 is:
6, 3, 0, 2 మరియు 8 అంకెలతో ఏర్పడిన అతిపెద్ద 5-అంకెల సంఖ్య మరియు అతి చిన్న 5-అంకెల సంఖ్యల మొత్తం:

A) 1,09.388
B) 1,06,688
C) 1,03,574
D) 88,688

View Answer

B) 1,06,688

Explanation:
Step 1: Form the greatest 5-digit number
To form the greatest 5-digit number, arrange the digits in descending order:8, 6, 3, 2, 0 ⇒ 86320
Step 2: Form the smallest 5-digit numberTo form the smallest 5-digit number, arrange the digits in ascending order.
2, 0, 3, 6, 8 ⇒ 20368
Step 3: Add the two numbers
Now, we add the greatest and smallest 5-digit numbers:
86320 + 20368 = 106688

102) The cost of fencing a square park of side 150m at the rate of ₹25 per meter is:
150 మీటర్ల చతురస్రాకార పార్క్ కు చుట్టూ కంచె వేయుటకు మీటరు ₹25 చొప్పున అయ్యే ఖర్చు:

A) ₹7500
B) ₹37500
C) ₹22500
D) ₹15000

View Answer

D) ₹15000

Explanation:To find the cost of fencing a square park, we need to calculate the perimeter of the park and then multiply it by the cost per meter of fencing.
Step 1: Find the perimeter of the square park
The perimeter ( P ) of a square is given by the formula:
P = 4 X (side length)
Given the side length is 150 meters, the perimeter is:
P = 4 X 150 = 600meters
Step 2: Calculate the cost of fencing
The cost of fencing is ₹25 per meter.
So, the total cost is:
Cost = Perimeter X {Cost per meter}
= 600 X 25 = 15000

103) $\frac23-\frac35$

A) $\frac1{15}$
B) $\frac12$
C) $\frac6{15}$
D) $-\frac12$

View Answer

A) $\frac1{15}$

Explanation:
To subtract the fractions $\frac{2}{3}$ and $\frac{3}{5}$ , we need to find a common denominator.
Step 1: Find the least common denominator (LCD) The denominators are 3 and 5.
The least common denominator of 3 and 5 is 15.
Step 2: Convert the fractions to have a denominator of 15
– For $\frac{2}{3}$ , multiply both the numerator and the denominator by 5: $\frac{2}{3} = \frac{2 \times 5}{3 \times 5} = \frac{10}{15}$
– For $\frac{3}{5}$ , multiply both the numerator and the denominator by 3: $\frac{3}{5} = \frac{3 \times 3}{5 \times 3} = \frac{9}{15}$
Step 3: Subtract the fractions
Now, subtract the fractions:
$\frac{10}{15} - \frac{9}{15} = \frac{10 - 9}{15} = \frac{1}{15}$

104) An angle with measure more than a right angle and less than a straight angle is:
లంబ కోణం కంటే ఎక్కువ మరియు సరళ కోణం కంటే తక్కువ కొలత కలిగిన కోణం:

A) Acute angle
అల్ప కోణం
B) Obtuse angle
అధిక కోణం
C) Reflex angle
పరావర్తన కోణం
D) Zero angle
శూన్య కోణం

View Answer

B) Obtuse angle

105) The median of one digit natural numbers is:
ఒక అంకె సహజ సంఖ్యల మధ్యగతం:

A) 4.5
B) 6
C) 5
D) 5.5

View Answer

C) 5

Explanation:The one-digit natural numbers are the numbers from 1 to 9:1, 2, 3, 4, 5, 6, 7, 8, 9
Step 1: Find the MedianThe median is the middle number in a sorted list. Since there are 9 numbers (an odd count), the median will be the number that is in the middle.
Step 2: Identify the Middle Number
The middle number in this list is the 5th number because:
{Middle number position} = $\frac{9 + 1}{2}$ = 5
