91) Which of the following is a non-terminating recurring decimal?
క్రింది వాటిలో అంతం కాని ఆవర్తితమయ్యే దశాంశం ఏది?

A) \( \frac{5}{8} \)

B) \( \frac{3}{7} \)

C) \( \frac{14}{35} \)

D) \( \frac{13}{16} \)

View Answer

B) \( \frac{3}{7} \)
Explanation:A rational number gives a terminating decimal only if the denominator (in lowest form) has prime factors 2 and/or 5 only.
1) 5/8 = 5/\( (2^3)\) → terminating
2) 3/7 → denominator has 7 → non-terminating recurring ✔
3) 14/35 = 2/5 → terminating
4) 13/16 = 13/\( (2^4)\) → terminating
92) If 3600 =\( 2^{x} \times 3^{y} \times 5^{z},\ \text{then } \frac{xy + yz + zx}{x + y + 2z} \)=
3600 =\( 2^{x} \times 3^{y} \times 5^{z} \text{అయితే } \frac{xy + yz + zx}{x + y + 2z} \)=

A) 3

B) 1

C) 2

D) 4

View Answer

C) 2
Explanation:3600 = 36 × 100
= \( (2^2 × 3^2)(2^2 × 5^2) \)
So, x = 4, y = 2, z = 2
(xy + yz + zx) / (x + y + 2z)
= (4×2 + 2×2 + 4×2) / (4 + 2 + 4)
= (8 + 4 + 8) / 10
= 20 / 10
= 2
93) Five years ago sum of the ages of Anitha and Sunitha is 42 years. Anitha is elder than Sunitha by 4 years. The ratio of present ages of Anitha and Sunitha is
ఐదు సంవత్సరాల క్రితం అనిత మరియు సునితల వయస్సుల మొత్తము 42 సంవత్సరాలు. సునిత కంటే అనిత 4 సంవత్సరాలు పెద్దది. అనిత మరియు సునితల ప్రస్తుత వయస్సుల నిష్పత్తి

A) 6:5

B) 8:7

C) 4:3

D) 7:6

View Answer

D) 7:6
Explanation:Let Sunitha's age 5 years ago be x.
Then Anitha's age = x + 4
x + (x + 4) = 42
2x = 38 → x = 19
Present ages:
Sunitha = 24 years
Anitha = 28 years
Ratio = 28 : 24 = 7 : 6
94) If cost of 5\( \left( \frac{1}{4} \right) \) dozens of apples is ₹1386, then the cost of 9 apples is
5\( \left( \frac{1}{4} \right) \) డజన్ల ఆపిల్ పండ్ల ధర ₹1386 అయితే, 9 ఆపిల్ పండ్ల ధర

A) ₹198

B) ₹225

C) ₹156

D) ₹204

View Answer

A) ₹198
Explanation:5¼ dozens = (21/4) × 12 = 63 apples
Cost of 63 apples = ₹1386
Cost of 1 apple = 1386 ÷ 63 = ₹22
Cost of 9 apples = 22 × 9 = ₹198
95) \( \frac{(0.2)^2 + (0.3)^2 + (0.4)^2}{(0.5)^2} = \)

A) 1.60

B) 1.24

C) 1.16

D) 1.08

View Answer

C) 1.16
Explanation:\( (0.2)^2 + (0.3)^2 + (0.4)^2 \)
= 0.04 + 0.09 + 0.16
= 0.29
\( (0.5)^2 = 0.25 \)
0.29 ÷ 0.25 = 1.16
96) Which of the following is correct?
క్రింది వానిలో ఏది సరైనది?

A) \( \frac{5}{6} + 1 = 1 \)

B) \( 2 + \frac{3}{4} = 2.75 \)

C) \( 4\,\frac{5}{6} = \frac{34}{6} \)

D) \( 3 – 1\,\frac{1}{2} = \frac{3}{4} \)

View Answer

B) \( 2 + \frac{3}{4} = 2.75 \)
Explanation:1) 5/6 + 1 = 11/6 ≠ 1 ❌
2) 2 + 3/4 = 2.75 ✔
3) 4 5/6 = 29/6 ≠ 34/6 ❌
4) 3 − 1 1/2 = 1.5 ≠ 3/4 ❌
97) Avani purchased a watch for ₹600 and sold it to Vikas at a gain of \( 6\,\frac{1}{2}\% \). Vikas sold it to Ashok at a gain of 15%. The amount paid by Ashok is
అవని ఒక గడియారాన్ని 7600లకు కొని, వికాస్ కు \( 6\,\frac{1}{2}\% \) లాభానికి అమ్మెను. వికాస్ ఆ గడియారాన్ని 15% లాభంతో అశోక్కు అమ్మెను. అశోక్ చెల్లించిన మొత్తము

A) ₹734.85

B) ₹746.40

C) ₹736.36

D) ₹739.63

View Answer

A) ₹734.85
Explanation:Let's go step-by-step.
Step 1: Understand the transactions.
– Avani bought the watch for ₹600.
– She sold to Vikas at a gain of \( 6 \frac{1}{2} \% \), i.e., \( 6.5\% \).
\( \text{Selling price for Avani} = 600 + 6.5\% \text{ of } 600 \)
\( = 600 + \frac{6.5}{100} \times 600 \)
= 600 + 39 = 639
So, Vikas bought it for ₹639.
Step 2: Vikas to Ashok.
– Vikas sold at a gain of 15%.
\( \text{Selling price for Vikas} = 639 + 15\% \text{ of } 639 \)
\( = 639 + \frac{15}{100} \times 639 \)
= 639 + 95.85 = 734.85
Step 3: Conclusion.
Ashok paid ₹734.85.
\( \boxed{1- ₹734.85} \)
98) Which of the following measures CANNOT form a triangle?
కింది కొలతలలో ఏది త్రిభుజాన్ని ఏర్పరచదు?

A) 7cm, 8cm, 9cm

B) 8cm, 8cm, 8cm

C) 6cm, 8cm, 10cm

D) 3cm, 6cm, 3cm

View Answer

D) 3cm, 6cm, 3cm
Explanation:Triangle rule: Sum of any two sides must be greater than the third.
3 cm + 3 cm = 6 cm (not greater than 6 cm)
So triangle cannot be formed.
99) In a triangle, the height is double the base and its area is 576 sq.cm. Then, it's height (in cm) is
ఒక త్రిభుజం ఎత్తు దాని భూమికి రెండు రెట్లు ఉంది. ఆ త్రిభుజ వైశాల్యం 576 చ.సెం.మీ. అయిన, ఆ త్రిభుజం ఎత్తు(సెం.మీ.లలో)

A) 36

B) 24

C) 48

D) 26

View Answer

C) 48
Explanation:Let base = x, height = 2x
Area = 1/2 × x × 2x = x²
x² = 576 → x = 24
Height = 2x = 48 cm
100) What does the height of the longest bar in the bar graph give?
కమ్మీ రేఖా చిత్రంలో అతి పొడవైన కమ్మీ యొక్క ఎత్తు దేనిని సూచిస్తుంది?

This is called the Mode.
Your Score: 0 / 0
