2022వ సంవత్సరంలో ఒక గ్యాస్ స్టవ్ ధర ₹4480.2023వ సంవత్సరంలో ఆ స్టవ్ ధర ₹5152 అయితే, సంవత్సరానికి గ్యాస్ స్టవ్ ధరలో పెరుగుదల శాతం ఎంత?

A) 15

B) 10

C) 25

D) 20

View Answer

A) 15
Explanation:Price in 2022 = ₹4480
Price in 2023 = ₹5152
Increase = 5152 − 4480 = 672
Percentage increase
= (672 ÷ 4480) × 100
= 15%
102) The complementary angle of supplementary angle of an angle is 54°.What is the measure of that angle?
ఒక కోణం యొక్క సంపూరక కోణం యొక్క పూరక కోణం 540.ఆ కోణం యొక్క కొలత ఏమిటి?

A) 54°

B) 144°

C) 36°

D) 126°

View Answer

B) 144°
Explanation:Let the angle be x
Supplementary angle = 180° − x
Complementary of supplementary angle
= 90° − (180° − x)
Given:
90 − 180 + x = 54
x − 90 = 54
x = 144°
103) In a rose garden, 15 rose plants have 15 flowers each.If Vani plucked 1/5 th part of them and decorated her room.Remaining rose flowers in the garden is
ఒక గులాబీ తోటలో, 15 గులాబీ మొక్కలు ఒక్కొక్కటి 15 పువ్వులు కలిగి ఉన్నాయి.వాటిలో 1/5 వ వంతు భాగాన్ని తెంచి, వాణి తన గదిని అలంకరిస్తే తోటలో మిగిలిన గులాబీ పువ్వుల సంఖ్య

A) 200

B) 45

C) 180

D) 90

View Answer

C) 180
Explanation:Total rose flowers
= 15 × 15 = 225
Plucked flowers
= (1/5) × 225 = 45
Remaining flowers
= 225 − 45 = 180
104) When the number of the faces of a cuboid is subtracted from the sum of its vertices and edges, the value is
దీర్ఘఘనం యొక్క ముఖాల సంఖ్యను దాని శీర్షాలు మరియు అంచుల మొత్తం నుండి తీసివేస్తే వచ్చే విలువ

A) 10

B) 12

C) 8

D) 14

View Answer

D) 14
Explanation:For a cuboid:
Vertices = 8
Edges = 12
Faces = 6
Sum of vertices and edges
= 8 + 12 = 20
Required value
= 20 − 6 = 14
105) How many weeks and days are there in a leap year?
లీపు సంవత్సరంలో ఎన్ని వారాలు మరియు రోజులు ఉంటాయి?

A) 53 weeks and 3 days

B) 52 weeks and 3 days

C) 53 weeks and 2 days

D) 52 weeks and 2 days

View Answer

D) 52 weeks and 2 days
Explanation:Weeks and days in a leap year
A leap year = 366 days.
Number of weeks: 366 \div 7 = 52 weeks and remainder days.
366 = 52 \times 7 + 2
So 52 weeks + 2 days.
Correct option: 52 weeks and 2 days
106) The mode of the numbers 9, 6, 4, 6, 3, 4, 3, 1, 5, 2, 1, 3 is:
సంఖ్యలు 9, 6, 4, 6, 3, 4, 3, 1, 5, 2, 1, 3 యొక్క బాహుళకం:

A) 4

B) 3

C) 6

D) 1

View Answer

B) 3
Explanation:Given numbers:
9, 6, 4, 6, 3, 4, 3, 1, 5, 2, 1, 3
Frequencies:
1 → 2 times
3 → 3 times
4 → 2 times
6 → 2 times
Mode = 3
107) The rational number that lies between \frac{5}{9} \text{ and } \frac{6}{7} from the following is
కింది వాటిలో \frac{5}{9} \text{ మరియు } \frac{6}{7} ల మధ్య ఉండే అకరణీయ సంఖ్య

A) \frac{15}{16}

B) \frac{2}{5}

C) \frac{13}{16}

D) \frac{15}{17}

View Answer

C) \frac{13}{16}
Explanation:A rational number between \frac{5}{9} and \frac{6}{7}
First convert to decimals to compare range:
\frac{5}{9} \approx 0.555\ldots
\frac{6}{7} \approx 0.857\ldots
We want a fraction between 0.555… and 0.857…
Check each option:
\frac{15}{16} = 0.9375 → greater than 0.857 → ❌ not in between
\frac{2}{5} = 0.4 → less than 0.555 → ❌
\frac{13}{16} = 0.8125 → between 0.555… and 0.857… ✅
\frac{15}{17} \approx 0.882 → slightly greater than 0.857 → ❌ (actually 15/17 = 0.88235…, greater than 6/7 ≈ 0.85714)
So only \frac{13}{16} works.
108) The no.of cubes with edge 3cm can be made from a cuboid of dimensions 15cm × 12cm × 9cm are
15సెం.మీ.× 12 సెం.మీ.× 9 సెం.మీ.కొలతలు కలిగిన దీర్ఘఘనం నుండి 3 సెం.మీ.అంచు ఉండేలా తయారు చేయగల ఘనాల సంఖ్య

A) 48

B) 24

C) 28

D) 60

View Answer

D) 60
Explanation:Dimensions of cuboid
= 15 × 12 × 9
Volume of cuboid
= 15 × 12 × 9 = 1620
Volume of one cube (edge 3 cm)
= 3 × 3 × 3 = 27
Number of cubes
= 1620 ÷ 27 = 60
109) The difference between 8563 and the number obtained by reversing its digits is
8563 మరియు దాని అంకెలను కుడి నుండి ఎడమకు రాయడంలో పొందిన సంఖ్యల మధ్య వ్యత్యాసం

A) 4905

B) 5115

C) 4995

D) 5015

View Answer

A) 4905
Explanation:Original number = 8563
Reversed number = 3658
Difference
= 8563 − 3658 = 4905
110) The number of \frac{1}{16} \text{ in } \frac{1}{2} is
\frac{1}{2} లో ఉన్న \frac{1}{16} ల సంఖ్య

A) 4

B) 8

C) 16

D) 2

View Answer

B) 8
Explanation:Number of \frac{1}{16} in \frac{1}{2}
= \frac{1}{2} ÷ \frac{1}{16}
= \frac{1}{2} × 16
= 8
